Question

Solver system of equations 6x - 3y = -6 9x - 3y = -18

Answer 1

To solve this system of equations, we will use the method of substitution or elimination.

Given equations:
1) 6x - 3y = -6
2) 9x - 3y = -18

Let's subtract equation 1 from equation 2 to eliminate y:

(9x - 3y) - (6x - 3y) = -18 - (-6)
3x = -12
x = -4

Now that we have the value of x, we can substitute it back into either of the original equations to solve for y. Let's use equation 1:

6(-4) - 3y = -6
-24 - 3y = -6
-3y = 18
y = -6

Therefore, the solution to the system of equations is x = -4 and y = -6.
