Solve : 0.4(3x -1) = 0.5x + 1

Solution:

Given, the equation is 0.4(3x -1) = 0.5x + 1

We have to solve the equation.

On solving the equation for x,

0.4(3x) - 0.4(1) = 0.5x + 1

1.2x - 0.4 = 0.5x + 1

By transposing,

1.2x - 0.5x = 1 + 0.4

0.7x = 1.4

x = 1.4/0.7

x = 2

Therefore, the value of x is 2.
