Answer:
given equations :-
3x+2y=11 ---------(1)
2x+3y=4----------(2)
by elimination method
2(3x+2y=11)
3(2x+3y=4)
6x+4y=22
6x+9y=12
________
-5y=10
________
(6x,6x get cancell)
-5y=10
y=10/-5
y=-2
substute y value in equation 1
3x+2(-2)=11
3x-4=11
3x= 11+4
3x= 15
X=15/3
X=5
therefore X = 5;y= -2
hope this helps u

Answer:
x=5 and y=-2
Step-by-step explanation:
3x+2y=11
2x+3y=4
by adding them
5x+5y=15
x+y=3
x=3-y
put the value of x
3x+2y=11
3(3-y)+2y=11
9-3y+2y=11
9-y=11
-y=11-9
-y=2
y=-2
put the value of y
x=3-y
x=3-(-2)
x=3+2
x=5
hence x=5 and y=-2
HOPE IT HELPS YOU!
