5. Use the equation y=4-3x to find when y: x=4 x= -3 x=2 x= -43

Step-by-step explanation:

x = 4

y = 4-3(4) = -8

x = -3

y=4-3(-3) = 13

x= 2

y= 4-3(2) = -2

x = -43

y = 4 - 3(-43) = 133

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
