5x-2y=7x-3y=4
substitusikan:
x-3y=4
x-3y+3y=4+3y
x=4+3y
5x-2y=7
5(4+3y)-2y=7
20+15y-2y=7
15y-2y=7-20
13y=-13
y=-1
smoga bermanfaat:)
Fllw me yah, makasii
x = 3y + 4
disubtitusikan
5x - 2y = 7
5(3y+4) - 2y = 7
15y + 20 - 2y = 7
13y = 7-20
y = -13/13
y = -1
x = ..... ?
x-3y = 4
x - 3(-1) = 4
x + 3 = 4
x = 1
x = 1
y = -1
