Question

−5x−5y= −30 10x+3y= −3

Answer 1

(-3, 9) is the intercepting point of the two lines.

Answer 2

x = -3, y = 9

Explanation:

-5x - 5y = -30

x - y = 6

x = -y + 6

10x + 3y = -3

10(-y + 6) + 3y = -3 (plug in x from the previous equation)

60 - 10y + 3y = -3

60 - 7y = -3

-7y = -63

y = 9

x = -y + 6

x = -(9) + 6

x = -3
