2) The given equation is expressed as
3(5x - 8) = - 5(- x + 7)
The first step is to open the brackets on both sides of the equation by multiplying the terms inside the bracket by the term outside. Thus, we have
3 * 5x + 3 * - 8 = - 5 * - x + - 5 * 7
15x - 24 = 5x - 35
By collecting like terms, we have
15x - 5x = - 35 + 24
10x = - 11
x = - 11/10
x = - 1.1
