Answer:
Explanation:
To solve the system of equations:
y = -x + 2
x - 3y = -18
We can use substitution or elimination method. Let's solve it using the substitution method:
From equation 1, we have y = -x + 2. We can substitute this value of y into equation 2:
x - 3(-x + 2) = -18
Simplifying:
x + 3x - 6 = -18
4x - 6 = -18
4x = -18 + 6
4x = -12
x = -12/4
x = -3
Now, substitute this value of x back into equation 1:
y = -(-3) + 2
y = 3 + 2
y = 5
So the solution to the system of equations is x = -3 and y = 5.
