What is the value of y=7— 2x when x
=4?

y=-1

Step-by-step explanation:

y=7-2x      x=4

plug in x : y=7-2*4

y=7-8

y=-1

-1

Step-by-step explanation:

-2 times 4 = -8

7-8=-1

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
