Question

2. Three more than four times a number is 15.

Answer 1

The number is 3

Explanation:

Let the number be x

Four times a number = 4 *x = 4x

Three more than four times a number = 4x + 3

4x +3 = 15

Subtract 3 from both sides

4x + 3 - 3 = 15 -3

4x = 12

Divide both sides by 4

4x/4x = 12/4

x = 3
