Question

What does i2x + 3(x - 5) = 20 equal

Answer 1

x = 5

Explanation:

2x + 3(x - 5) = 20

simplify

5x - 5 = 20

get the variable and the number on different sides

5x - 5 + 5 = 5x

20 + 5 = 25

5x = 25

now divide each side by 5

5x / 5 = x

25 / 5 = 5

x = 5

Answer 2

x=7

Explanation:

2x+3(x-5)=20

2x+3x-15=20

5x-15=20

5x=35

x=7
