Yes, (-6, -8) is a solution to the system of equations.
When x = -6 and y = -8:
18(-6) - 15(-8) = 12
-108 + 120 = 12
6(-6) - 6(-8) = 12
-36 + 48 = 12
Therefore, (-6, -8) satisfies both equations in the system and is a solution.
Is (-6, -8) a solution to this system of equations?
18x–15y=12
6x–6y=12
