I assume you mean 3y+2x+1. So sub in the points and see. The 1 is x and the -3 is y.
3(-3) + 2(1) + 1. Does this equal 0? -9+2+1 equals -6, so no, it is not a solution. For example, if your point is (1,-1), this would be a solution.

What is the oxidation number of C2H4O?
C2H4O oxidation number is -1 2x+1(4)+1(-2)=0 2x+4-2=0 2x+2=0 2x=-2 x=-2/2 x=-1
How can prepare 10 percent ammonia solution from 26 percent ammonia solution?
Check what it is dissolved in first and use the same solvent for dilution. If you want to make a litre of 10% for instance, You want to dilute it 10 in 26 parts or 5 in 13. So 1 litre /13*5 is 384.6ml of 26% ammonia, and dilute to 1 litre with solvent
A solution is tested and found to have a pH of 1 the solution is?
This solution is acidic.
Calculate the pH of 0.01m hcl?
HCl is a strong acid, so we assume that it completely breaks up into ions in solution. HCl ----> H+ & Cl- if we have 0.01m of HCl, it will give 0.01m of H+ and 0.01m Cl- pH = -log [H+] pH = -log 0.01 pH = 2
How many times a solution of pH 1 will be stronger than that of a solution having pH 2?
how many times a solution of ph 1 will be stronger than that of a solution having ph 2
1- Which of the ordered pairs is a solution of 2x plus 3y equals 13?
2x plus 3y
Is (1 1) a solution to 3y 2x 1?
Yes if you mean (1, 3) and 3y = 2x+1
How do you solve 2x plus 1 equals 3y and 4 equals 3y-10 by elimination?
1) 2x + 1 = 3y 2) 4 = 3y - 10 this can be re-written as 3y = 4 + 10 Therefore 2x + 1 = 4 + 10 2x = 13 x = 6.5 Sustitute x = 6.5 in equation 1) above 2x + 1 = 3y 2 (6.5) + 1 = 3y therefore 3y = 13 +1 3y = 14 y = 14/3 Now substitute y = 14/3 in equation 2) above and watch what happens! 4 = 3(14/3) -10 4 = 4 Therefore the answer is correct!
How do you factor 12x2-27y2?
3(2x + 3y)(2x - 3y)
What the solution of 2x plus 5y equals 16 and 2x plus 3y equals 14?
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
How do you do this problem 2x plus 3y equals 1?
2x + 3y = 1 y = 1/3 - 2x/3
How to graph -2x plus 3y equals 1?
-2x+3y=1 3y=1+2x y=(1+2x)/3 Then proceed to find points by plugging in given or arbitrary values of x.
What is the solution to this system of equations 6x-3y -33 2x y -1 using substituition?
If you mean: 6x-3y = -33 and 2x+y = -1 Then solving the simultaneous equations by substitution: x = -3 and y = 5
How Do you Graph The Following Equation -2x plus 3y equals 1?
-2x plus 3y equals 1
If 2x-3y equals -1 and 3x plus 2y equals 31 find the values of x and y?
2x - 3y = -1 3x + 2y = 31 eqn(1) * 2: 4x - 6y = -2 eqn(2) * 3: 9x + 6y = 93 Add the two: 13x = 91 Divide both sides by 13: x = 7 Substitute this value of x into eqn(1): 14 - 3y = -1 Add 3y to bot sides: 14 = -1 + 3y Add 1 to both sides: 15 = 3y Divide both sides by 3: 5 = y So the solution is x = 7, y = 5
Is (-5 -1) a solution to this system of equations 3y -2x and ndash 13 -4x -8y plus 12?
Without any equality signs the given terms can't be considered to be equations.
If 5 comma1 is a solution to the equation 2x minus 3y equals 7 What does this mean?
You are looking for the solution to the function 2x - 3y = 7.This means that when you substitute 5 for x and 1 for y, the equation makes sense logically.(2*5) - (3*1) = 10 - 3 = 7.This makes sense logically.
