To solve the equation you should separate x on one side and the number on the other side, then make the coefficient of x = 1
Let us do that
Multiply the bracket by 1/4 first
[tex]\frac{1}{4}(16x+60)=\frac{1}{4}(16x)+\frac{1}{4}(60)=4x+15[/tex]So the equation will be
9x - 5 = 4x + 15
Add 5 to both sides to move 5 from the left hand to the right hand
9x - 5 + 5 = 4x + 15 + 5
9x = 4x + 20
Now subtract 4x from both sides to move x
