Answer:
x = 5;y= -2
Step-by-step explanation:
given equations :-
3x+2y=11 ---------(1)
2x+3y=4----------(2)
by elimination method
, we multiply 2 to(1) and 3 to (2):
2(3x+2y=11)
3(2x+3y=4)
6x+4y=22
-
6x+9y=12
________ (6x,6x get cancell)
-5y=10
________
-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
