6x-14x+16=27+11
answer: 4
-11
It is an equation and the value of x is 4
(x - 3)(x - 11)
11 So: x = 37
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
x=4
-11
Standard form is y = mx + b where m = slope 2y = -14x + 22 divide both sides by 2 y = = -7x + 11 slope = m = -7
6x - 14x = 35 + 11 -8x = 46 8x = -46 8x/8 = -46/8 x = -5.75
14x + 11
Equations: 7x+4y = 9 and 2x+3y = 1 Multiply all terms in the 1st equation by 2 and all terms in the 2nd equation by 7 So: 14x+8y = 18 and 14x+21y = 7 Subtract the 1st equation from the 2nd equation: 13y = -11 => y = -11/13 By substituting y = -11/13 into any of the equations x = 23/13 Therefore the solutions are: x = 23/13 and y = -11/13
3d + 14 = 11 is the equation.
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
It is an equation of a straight line.
8x-11+6x = -151 8x+6x = -151+11 14x = -140 x = -10
4
It is an equation and the value of n is 9
