Answer: x = 4, y = 5
Explanation:
To solve by elimination, we must first eliminate one of the variables of the equations. We'll get rid of y, and to do this, you have to multiply 2x - y = 3 by -6.
-6(2x - 7 = 3)
-12x + 6 = -18
Now add -12x + 6 = -18 to with 9x - 6y = 6 to get rid of y.
-3x = -12 Solve for x
x = 4
Now plug x back into the original equation to solve for y.
2(4) - y = 3
8 - y = 3
-y = -5
y = 5
Your final solution is (4, 5)
