The give equation is expressed as
4x + 5(7x - 3) = 9(x - 5)
The first step is to open the bracket by multiplying the terms inside the bracket with the term outside. It becomes
4x + 5 * 7x + 5 * - 3 = 9 * x + 9 * - 5
4x + 35x - 15 = 9x - 45
Collecting like terms, it becomes
4x + 35x - 9x = - 45 + 15
30x = -30
x = -30/30
x = 1
