Answer 1

Verified answer

X+3y = 10 (×2) 2x+6y = 20
2x-y = 6 (×1) 2x-y = 6
(dieliminasi)
7y = 14
y=2

x+3y = 10
x+3 (2) = 10
x+6 = 10
x=4

Answer 2

Verified answer

X + 3y = 10
x = 10 - 3y

2x - y = 6
2(10 - 3y) - y = 6
20 - 6y - y = 6
20 - 6 = 7y
y = 14/7
y = 2

x = 10 - 3y
x = 10 - 3.2
x = 4

(x,y) = (4,2)
