Question

What is the solution to the equation?

5(8 + 7) = 5 • x + 5 • 7

A.
x = 1

B.
x = 5

C.
x = 7

D.
x = 8

Answer 1

So we have the equation 5(8+7)=5x+(5)(7)

Step 1: Simplify both sides of the equation.

75=5x+35

Step 2: Flip the equation.

5x+35=75

Step 3: Subtract 35 from both sides.
5x+35−35=75−35
5x=40

Step 4: Divide both sides by 5.
5x5=405
x=8

Answer:
x=8

Answer 2

The answer would be 8.

Step 1: Simplify both sides of the equation.
75=5x+35
Step 2: Flip the equation.
5x+35=75
Step 3: Subtract 35 from both sides.
5x+35−35=75−35
5x=40
Step 4: Divide both sides by 5.
5x/5=40/5

x=8
