Start with the first equation.
Multiply both sides by 2.
Distribute
Multiply
Plug in . In other words, replace each '2x' with 'y-13' (that's why I multiplied both sides by 2 above).
Combine like terms on the left side.
Add to both sides.
Combine like terms on the right side.
Divide both sides by to isolate .
Reduce.
Move onto the second equation
Plug in
Subtract
Divide both sides by to isolate .
Reduce.
