Question

What’s the answer to 13x+7= 8x+27 ?

Answer 1

x = 4

Explanation:

Subtract 8x from both sides

13x+7−8x=8x+27−8x

5x+7=27

Subtract 7 from both sides

5x+7−7=27−7

5x=20

Divide both sides by 5

5x/5 = 20/5

x = 4

Answer 2

x = 4

Explanation:

Isolate the x:

13x + 7 = 8x + 27

subtract 7 from both sides:

13x = 8x + 20

subtract 8x from both sides:

5x = 20

divide both sides by 5:

x = 4
