We have been given a system of equations. 
and 
. We are asked to find the solution of our given system of equations.
The solution of our given system of equations will be the point, where both lines will intersect.
To find intersection point, we will equate both equations as:
Now we will substitute in equation and solve for y.
Therefore, the point 
is the solution of our given system of equations.
We can verify our answer by graphing both equations.
The answer would be 70 6•8=48 2.75•8=22 and 48+22=70
