-2x + 2y = 10
2x - 10y = -18

Answer 1

Answer:

The answer is (4,1)

Step-by-step explanation:

-2x + 2y = 10

-2x = 10 - 2y

2x = 2y - 10 ---------------- (i)

2x - 10 = -18

Substitute (i)

(2y - 10) - 10 = -18

2y - 20 = -18

2y = -18 +20

2y = 2

y = 1

2x + 10y = 18

2x + 10(1) = 18

2x + 10 = 18

2x = 18 - 10

2x = 8

x = 4

The answer is (4,1)
