, so we can plug this equation into the first to obtain:

. The second equation is simply put in the place of the

in the first equation.
To solve this, combine the

terms on the left hand side of the equation:

.
Then, subtract the 3 from both sides:

.
To obtain what

equals, divide both sides by 4:

.
This result can then be plugged back into the second equation to determine that

is equal to.
So:

Which yields:

.
Our answer is then
