`-x + 3y = 17, 4x + 3y = 7` Use any method to solve the system.
To solve this system of equation, let's apply substitution method. To do so, isolate the x in the first equation.
`x=-17 + 3y`
Then, plug-in this to the second equation.
And, solve for y.
Now that the value of y is known, solve for x. Plug-in y = 5 to the first equation.
Therefore, the solution is (-2,5).
