Answer:
(1, 5)
Step-by-step explanation:
Substitution works well here. Solving the second equation for x, we get x = y - 4. Substituting y - 4 for x in the first equation results in
-3(y - 4) + y = 2.
Next, we perform the indicated multiplication and obtain:
-3y + 12 + y = 2, or -2y = -10
Dividing both sides by -2 yields y = 5. As seen above, x = y - 4; if y = 5, then x = 5 - 4 = 1.
The solution is (1, 5)
