For this case we have an equation with two variables, "x" and "y". Also, we have that the value of "x" is given by:
. We must find the ordered pair of the solution of the equation.
Let: ![\frac {2} {3} x + y -1 = 0](/tpl/images/0497/7650/cf6a2.png)
We substitute
in the equation:
![\frac {2} {3} (- 6) + y -1 = 0\\-4 + y-1 = 0\\y = 1 + 4\\y = 5](/tpl/images/0497/7650/c3ffe.png)
Thus, the ordered pair that is the solution of the equation
is![(x, y) = (- 6,5)](/tpl/images/0497/7650/9aee9.png)
![(x, y) = (- 6,5)](/tpl/images/0497/7650/9aee9.png)
