The given equation is expressed as
4(x - 3)= 16 - 3x
The first step is to expand the parentheses on the left by multiplying the terms inside the parentheses with the term outside. We have
4x - 12 = 16 - 3x
The nest step is to add 3x and 12 to both sides of the equation. We have
4x + 3x - 12 + 12 = 16 + 12 - 3x + 3x
7x = 28
Dividing both sides of the equation by 7, we have
7x/7 = 28/7
x = 4
