Which property is not used to simplify the following expression?
2. (x + 5) + 7x = (2x + 10 + 7x
= (10 + 2x) + 7 x
= 10 + (2x + 7x)
= 10 + 9x
9x +
associative property of addition
commutative property of addition
commutative property of multiplication
distributive property

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
