Simplifying algebraic exspressions 1) 9(-7b-5)

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

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
