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

Answer:
The number is 3
Step-by-step 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
