Answer:

(3,-2)

Step-by-step explanation:

Part A:

1) Isolate x in x - y = 5

x = y + 5

2) Substitute that x into 4x+y=10

4(y + 5) + y = 10

4y + 20 + y = 10

5y = 10-20

5y = -10

y = -2

3) Use y to solve for x:

x = -2 + 5

x = 3

Part B:

Verify using results from Part A

3 - (-2) = 5

4(3) + (-2) = 12 - 2 = 10

Part C:

Just graph the equations and see where they intersect, which is exactly (3,-2). We got that in Part A and B
