Answer:
x= 1 and y=2
Step-by-step explanation:
By elimination method,
x+2y=5.......eq.(1)
2x+y=4.......eq.(2)
Multiplying eq.(1) with 2
=>2(x+2y)=2(5)
=>2x+4y=10.......eq.(3)
Subtracting eq.(2) from eq.(3)
=>2x+4y-(2x+y)=10-4
=>2x+4y-2x-y=6
=>3y=6
=>y=2
x=1

X+2y=5 2X+y=4
X=5-2y 2X+y=4
to find value of y
2x5-2y+y=4
10-3y=4
10-4=3y
6=3y
y=6/3
y=3
now
X=5-2x2
X=5-4
X=1
1+2x2=5
2x1+2=4
X=5-2y 2X+y=4
to find value of y
2x5-2y+y=4
10-3y=4
10-4=3y
6=3y
y=6/3
y=3
now
X=5-2x2
X=5-4
X=1
1+2x2=5
2x1+2=4
