All of the following expressions simplify to -5x+7, except
(4x+3)+(-9x+4)
(x - 2) - (6x-9)
(5x + 1) - (-10x+6)
o-4x+2x+7 - 3x

(5x+1)-(-10x+6)

Step-by-step explanation:

Since there is a negative in front of a parenthesis , multiply by -1. It would be 5×+1+10x-6. Add like terms, it would be 15x-5

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
