4(x+8) -4= 34 -2x
⇒ 4x+ 32 -4= 34 -2x (distributive property)
⇒ 4x + 28= 34 -2x
⇒ 4x+ 2x= 34-28
⇒ 6x= 6
⇒ x= 6/6
⇒ x= 1
Final answer: x=1

Let's begin with the left side of the equation.
4(x + 8) -4 - Distributive Property.
4x + 28 = 34 - 2x - Add 2x to both sides.
6x + 32 = 34 - Subtract 28 from both sides.
6x = 6 - Divide by 6 on both sides.
x = 1
