What are the solutions to this system why equals x + 3x - 4 y = 2x + 2

Answer 1

To find the solutions to the system of equations, we need to solve for the values of x and y that satisfy both equations simultaneously.

Given:
1) x - y = 4
2) y = 2x + 2

Substitute the expression for y from the second equation into the first equation:
x - (2x + 2) = 4
x - 2x - 2 = 4
-x - 2 = 4
-x = 6
x = -6

Now that we have found the value of x, substitute it back into the second equation to find the value of y:
y = 2(-6) + 2
y = -12 + 2
y = -10

So, the solutions to the system of equations are x = -6 and y = -10.
