Answer:
x= 2; y= 1
Step-by-step explanation:
2x+y=5 ...equation 1
3x+2y=8 ...equation2
multiply: equation 1*2 & equation 2*1
now, equation 1=> 4x+2y=10
and, equation 2=> 3x+2y= 8
subtract: equation 2-equation 1
4x+2y=10
-3x-2y= -8
________
x= 2 (+2y and -2y got cancelled while 4x-3x=1x)
putting x= 2 in equation 1
2(2) +y=5
4+y=5
y=5-4
y= 1
Verification:
2(2)+1=5
4+1=5
5=5
LHS=RHS
