Set up the equation and solve.
Twice a number increased by 12 is 20. What is the number?

2x+12 = 20

x = 4

Step-by-step explanation:

Twice a number = 2x

increased by 12 = +12

Format:

2x + 12 = 20

Solve

Subtract 12 from both sides

2x + 12 - 12 = 20 - 12

2x = 8

divide both sides by 2

2x/2 = 8/2

x = 4
