Question

Tolong ya dengan jalan subtitusi


mohon dengan cara nya

Answer 1

A.
x+4y-6=0
x=6-4y

2x-y-3=0
2(6-4y)-y-3=0
12-8y-y-3=0
9y=9
y=1

x=6-4(1)=2

b.
+2y-5=0
x=5-2y

2x+y+2=0
2(5-2y)+y+2=0
10-4y+y+2=0
3y=12
y=4

x=5-2.4=-3

Answer 2

X+4y-6 = 0
2x-y-3 = 0
___________-
-x+5y-3 = 0
5y-3 = x
x+4y -6 = 0
5y-3 +4y = 6
9y = 9
y = 1
x = 2



x+2y -5 =0
2x+y+2 = 0
____________-
-x+y-7 = 0
y-7 = x
y-7+2y - 5 = 0
3y = 12
y = 4
x = 1
