To solve this system of equations, since y is already isolated in both equations, you can set the expressions to equal each other to solve for x:
-x + 2 = - 5x - 6
-x + 5x = - 6 - 2
4x = - 8
x = - 2
Now that we have x, we can substitute it into one of the equations to find y:
y = - (-2) + 2
y = 2 + 2
y = 4
The last step is to substitute both values into both equations to see if they are correct:
4 = - (-2) + 2 - - > 4 = 2 + 2 <--True
4 = - 5 (-2) - 6 - - > 4 = 10 - 6 <--True
Answer:
x = - 2
y = 4
