Solve : 10x - 5 - 7x = 5x + 15 - 8

Solution:

Given, the equation is 10x - 5 - 7x = 5x + 15 - 8

We have to solve the equation

On solving the equation for x,

10x - 5 - 7x = 5x + 15 - 8

By grouping of common terms,

10x - 7x - 5 = 5x + 15 - 8

(10 - 7)x - 5 = 5x + (15 - 8)

3x - 5 = 5x + 7

By transposing,

3x - 5x = 7 + 5

x(3 - 5) = 12

-2x = 12

x = 12/-2

x = -6

Therefore, the value of x is -6.
