20 (x+2) + 31=5 (5x+10) + 13

x = 8 / 5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20 (x+2) + 31=5 (5x+10) + 13

(20) (x) + (20) (2) + 31 = (5) (5x) + (5) (10) + 13 (Distribute)

20x+40+31=25x+50+13

(20x) + (40+31) = (25x) + (50+13) (Combine Like Terms)

20x+71=25x+63

20x+71=25x+63

Step 2: Subtract 25x from both sides.

20x+71-25x=25x+63-25x

-5x+71=63

Step 3: Subtract 71 from both sides.

-5x+71-71=63-71

-5x=-8

Step 4: Divide both sides by - 5.

-5x / - 5 = - 8 / - 5

x = 8 / 5
