Solve : (0.2x + 5)/(3.5x - 3) = 2/5.

Solution:

Given, the equation is (0.2x + 5)/(3.5x - 3) = 2/5

We have to solve the equation.

On solving the equation for x,

0.2x + 5 = 2(3.5x - 3)/5

5(0.2x + 5) = 2(3.5x - 3)

1x + 25 = 7x - 6

By transposing,

7x - x = 25 + 6

6x = 31

x = 31/6

Therefore, the value of x is 31/6.

✦ Try This: Solve : (0.3x + 3)/(1.5x - 1) = 1/4.
