Answer:
x = 8
y = 3
Explanation:
y = x - 5
y = -1/2 x + 7 Set the equations equal to each other and solve for x
-1/2 x + 7 = x - 5 Multiply all the way through by 2 to clear the fraction
-x + 14 = 2x - 10 Add x to both sides
14 = 3x -10 Add 10 to both sides
24 = 3x Divide both sides by 3
8 = x
Substitute 8 for y in y = x - 5
y = 8-5 = 3
y = 3
