y = 1+2x
3x+(1+2x) = 11
...
3X+Y-11 and -2X+Y=1
X= Y=

Given
3x+y=11 call as eq 1
-2x+y=1 call as eq 2
Subtract 1&2 and consider simaltaneously
We get "y" will be cancelled
So, 5x=10
x=10/5
X=2
Substitute x=2 in eq 1
3x+y=11
3(2)+y=11
6+y=11
Y=11-6
Y=5
Therefore x=2 and y=5
3x+y=11 call as eq 1
-2x+y=1 call as eq 2
Subtract 1&2 and consider simaltaneously
We get "y" will be cancelled
So, 5x=10
x=10/5
X=2
Substitute x=2 in eq 1
3x+y=11
3(2)+y=11
6+y=11
Y=11-6
Y=5
Therefore x=2 and y=5
