Question

A number is first increased by 20 and then doubled. The result is 2 less than 5 times the number

Answer 1

set up an equation:

2(x+20) = 5x - 2

Simplify:

2x +40 = 5x - 2

Add 2 to both sides:

2x + 42 = 5x

Subtract 2x from both sides:

42 = 3x

Divide both sides by 3:

x = 42/3 = 14

The number is 14
