To solve this system of equations, we can use substitution.
We can start by substituting the expression for y from the second equation into the first equation:
2x + (2x + 4) = -8
Simplifying:
4x + 4 = -8
Subtracting 4 from both sides:
4x = -12
Dividing by 4:
x = -3
Now that we know x, we can substitute this value back into either equation to find y. Let's use the second equation:
y = 2(-3) + 4
y = -2
Therefore, the solution to the system of equations is x = -3 and y = -2.
2x + y = -8 y = 2x +4
