Question

Select the correct answer. Which value of x from the set {4, 5, 6, 7}, makes this equation true? 4(8 − x) = 8 4 5 6 7

Answer 1

4(8 - x) = 8, 32 - 4x = 8, -4x = -24, So x = 6

Explanation:

Answer 2

6

Explanation:

The set of 4, 5, 6, and 7 are the options for the inputs which will give 8 in the equation.

4(8-x) = 8.

For 4 times a number to be 8 it must be 2. This means (8-x)=2. Only 6 will satisfy. (8-6) = 2. and 4*2=8
