Question

Eva is solving the equation 4(x+32)=8

She says, “I can subtract 32 from each side to get 4x=132 and then divide by 4 to get x=138."

Dakota says, “I think you made a mistake.”

Determine the correct value for x.

x=

Answer 1

The correct answer is -30

Explanation:

4(x+32)=8 basically you multiply 4 times the numbers that are in the parentesis which that will equals to 4x+128 because 4x1= 4x and 4x32 = 128. then you subtract 128 from 8 which equals to -120. you divide -120 by 4 which equals to -30.
