1.25(4x-10)=7.5

5x-12.5=7.5

5x=20 x=4

Answer 2

Given:

Equation - 1.25 (4x-10) = 7.5

To Find:

Value of x for which 1.25 (4x-10) = 7.5 is true.

Solution:

We have given Equation - 1.25 (4x-10) = 7.5

so,

⇒  1.25 (4x-10) = 7.5

⇒ (4x-10) = 7.5 / 1.25

⇒ (4x-10) = 6

⇒ 4x = 6 + 10

⇒ 4x = 16

⇒ x = 16/4

⇒ x = 4

Hence, the value of x is 4.
