Answer 2

The value of x is 2.

Given:

0.15(5x-2) = 0.4(x+1)

To find: x

Solution:

We are given that,

0.15(5x-2) = 0.4(x+1)

Opening the brackets,

⇒ 0.75x - 0.30 = 0.4x + 0.4

Transposing variable terms to the left and constants to the right,

⇒ 0.75x - 0.4x = 0.4 + 0.3

⇒ x(0.75 - 0.4) = 0.7

⇒ 0.35x = 0.7

⇒ x = 0.7/0.35

Multiplying the numerator and denominator by 100, we get

⇒ x = 70/35

⇒ x = 2
