Answer:

x = 5, y = 4

Step-by-step explanation:

Solve for one variable. x will be simpler using the second equation.

3x = 15

Divide by 3.

x = 5.

Now put that into the other equation.

4x + 5y = 40

Substitute variable.

4(5) + 5y = 40

20 + 5y = 40

Subtract 20 from both sides.

5y = 20

Divide by 5.

y = 4.
