Question

Use the X method to find the solutions of
62 + 2x - 20 = 0.

Answer 1

x= -21

Explanation:

62+2x-20=0 Subtract the numbers

42+2x=0 move the constant to the right.

2x = -42 divide both sides by 2

x = -21

Answer 2

x = -21

Explanation:

62 + 2x - 20 = 0.

Combine like terms

42 +2x =0

Subtract 42 from each side

42-42 +2x = 0-42

2x = -42

Divide each side by 2

2x/2 = -42/2

x = -21
