Find the number

3

Step-by-step explanation:

Three more than the product of a number and 4 is 15.

3 + (x * 4) = 15

Multiply x by 4

3 + 4x = 15

Subtract 3 from both sides of the equation

4x = 12

Divide both sides of the equation by 4

x = 3

Step-by-step explanation:

Let the number be A

3 more than the product of A and 4 is 15

That’s

3 + (A x 4 ) = 15

3 + 4A = 15

Subtract 3 from both sides

3 - 3 + 4A = 15 - 3

4A = 12

Divide both sides by 4

A = 12/4

A = 3
