Start with the first equation.
Plug in into the second equation. In other words, replace each with . Notice we've eliminated the variables. So we now have a simple equation with one unknown.
Combine like terms on the left side
Add 5 to both sides
Combine like terms on the right side
Divide both sides by 3 to isolate x
Divide
Since we know that we can plug it into the equation (remember we previously solved for in the first equation).
Move onto the second equation.
Plug in
Multiply
Combine like terms
So the solutions are and
This means that the two numbers are 11 and 17
