Step-by-step explanation:

Let's solve the second equation for x

Now let's replace this in the first equation.

Distribute the 5

Individually solve the fractions.

Solve;

Subtract 20 from both sides.

Divide both sides by -7


Now replace the value of y in any of the two equations to find x.


add
