3x+2y=2 | x1 | 3x + 2y = 2
x-4y=10 | x3 | 3x-12y = 30
---------------------- -
14y = 28
y = 2
subtitusikan y
x - 4y = 10
x - 4.2 = 10
x - 8 = 10
x = 10+ 8
× = 18
maka x + y = 18 + 2
x + y = 20

3p + q = 7 | x2 | 6p + 2q = 14
4p+2q=12 | x1 | 4p + 2q = 12
----------------------- -
2p = 2
p = 1
subtitusikan p
3p + q = 7
3.1 + q = 7
q = 7 - 3
q = 4
maka 5p - q = 5.1 - 4
5p - q = 1
