Question

Which value of x makes the equation 1.25(4 x-10)=7.5 true?

A. 3.5
B. -1
C. -0.5
D. 4​

Answer 1

4

Explanation:

1.25(4x-10)=7.5

First step is to divide the 1.25 on both sides

4x-10 = 6

next step is to get x by itself by adding 10 to both sides

4x = 16

continue getting x by itself by dividing both sides by 4

x = 4.
