To solve this system of equations, we can use the method of substitution or elimination.
Let's use the elimination method here.
First, let's multiply the second equation by 5 so that the coefficients of x will be opposite and we can eliminate x when we add the two equations together.
5(-x + 3y) = 5(22)
-5x + 15y = 110
Now, we will add the two equations together
5x - 4y = -44
-5x + 15y = 110
___________________
11y = 66
y = 6
Now, we can substitute the value of y back into either of the original equations to solve for x. Let's use the first equation.
5x - 4(6) = -44
5x - 24 = -44
5x = -20
x = -4
Therefore, the solution to the system of equations:
5x - 4y = -44
-x + 3y = 22
is x = -4 and y = 6. The solution is (-4, 6).
