Question

Drag a reason to each box to complete this proof. If 1/2(8x +14) =39, then x = 8

Answer 1

Answer:

Correct, if 1/2(8x +14) =39, then x = 8

Step-by-step explanation:

$\frac{1}{2}(8x+14)=39$

Solving for x: Multiplying both sides of the equation by 2

$2[\frac{1}{2}(8x+14)]=2(39)\\ 8x+14=78$

Subtracting 14 from both sides of the equation:

$8x+14-14=78-14\\ 8x=64$

Dividing both sides of the equation by 8:

$\frac{8x}{8}=\frac{64}{8}\\ x=8$
