Solve : 3 (5x - 7) + 2(9x - 11) = 4(8x - 7) - 111

Solution:

Given, the equation is 3 (5x - 7) + 2(9x - 11) = 4(8x - 7) - 111

We have to solve the equation

On solving the equation for x,

3 (5x - 7) + 2(9x - 11) = 4(8x - 7) - 111

3(5x) - 3(7) + 2(9x) - 2(11) = 4(8x) - 4(7) - 111

15x - 21 + 18x - 22 = 32x - 28 - 111

15x + 18x - 21 - 22 = 32x - 139

33x - 43 = 32x - 139

By transposing,

33x - 32x = -139 + 43

x = -96

Therefore, the value of x is -96
