The answer is (drum roll) ... 104xy! It's 104xy I would think that 5x + 99y would equal 104xy. I may be wrong but i think that is the correct answer.
99y
5x + 10x doesn't need factorization as you can just add them up (5x+10x=15x). However, if you really want to, 5x+10x=5x(1+2)=5x(3)=15x
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
To multiply (5x) by (x^2), you multiply the coefficients and add the exponents of the variables. The coefficient is 5, and the exponent of (x) in (5x) is 1. So, (5x \times x^2 = 5x^{1+2} = 5x^3).
Adding monomials. Add together like terms. Example 4x + 5x. Add the coefficients. Example 4 + 5 = 9. Keep the base which was x. So the answer to 4x + 5x = 9x
How do you add 2x plus 3y equals 18 in 5x-y equals 11
5x - 8 = 7 Add 8 to both sides 5x = 15 Divide both sides by 5 x = 3
5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12
14x + 3
-5x+(3x-8)
5x-4 = 47 Add 4 to both sides: 5x = 51 Divide both sides by 5 to find the value of x: x = 10.2
5x + 6y + 3y - 2x you have to add like terms. add the y terms and then the x terms 9y + 3x this is your answer
