Solve : 5(x - 1) - 2(x + 8) = 0

Solution:

Given, the equation is 5(x - 1) - 2(x + 8) = 0

We have to solve the equation

On solving the equation for x,

5(x - 1) - 2(x + 8) = 0

5(x) - 5(1) - 2(x) - 2(8) = 0

5x - 5 - 2x - 16 = 0

By grouping of common terms,

5x - 2x - 5 - 16 = 0

(5 - 2)x - 5 - 16 = 0

3x - 21 = 0

By transposing,

3x = 21

x = 21/3

x = 7

Therefore, the value of x is 7.
