Question

Y= - x + 2
X - 3y = -18

Answer 1

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.
