Question 325103
4x + y = 11......1
x + 2y = 8 ......2
..
Equation 2
x+2y=8
add -2y
x+2y-2y=8-2y
x= 8-2y
..
4x+y=11
plug the value of x in this equation
4(8-2y)+y= 11
32-8y+y=11
Add -32 to both sides
-32+32-7y=11-32
-7y=-21
y=-21/-7
y=3
..
plug the value of x in the equation x+2y=8
x+6=8
x=8-6=2
x=2
