What is the solution to the system of equations below?
1 answer:
Answer:
(x, y) = (-4, -15)
Step-by-step explanation:
You can equate the expressions for y and solve for x.
3/4x -12 = -4x -31
Adding 4x+12 gives ...
(4 3/4)x = -19
(19/4)x = -19
Multiplying by 4/19, we find ...
x = -4
Substituting that into the first equation, we can find y:
y = (3/4)(-4) -12 = -15
The solution is (x, y) = (-4, -15).
