To solve the system of equations using substitution, we first solve one equation for one variable and then substitute that expression into the other equation.
From the first equation, we can solve for
Now we substitute this expression for
Now that we have found
Therefore, the solution to the system of equations is
From the first equation, we can solve for
in terms of
:
Now we substitute this expression for
into the second equation:
Now that we have found
, we can substitute it back into the expression for
:
Therefore, the solution to the system of equations is
and
