Answer:
D)
Step-by-step explanation:
First, let's rearrange the first equation in order to use the substitution method:
3x - y = 12
Add y to each side:
3x = 12 + y
Subtract 12 from both sides:
3x - 12 = y
y = 3x - 12
Then use substitution to solve for y:
From my perspective, this is the farthest you can get until you can solve, so there is not enough information to solve this.
