To solve this system of equations, we can start with the first equation. Simplifying
gives us
. Now, let’s substitute this expression for
into the second equation
. This becomes:
Simplifying this, we get:
Multiply both sides by 2:
Adding 3 to both sides:
Dividing by 2:
Now we can substitute
back into the equation
:
Thus, the solution to the system of equations is
.
