Answer:
x=6 and y=2
Step-by-step explanation:
2x+3y=18......(i)
x-2y=2....... (ii)
here you can multiply the equation (i) with1 and (ii) with 2
now
2x+3y=18
2x-4y=4
(-). (+). = (-)
then
0+7y=14
7y =14
y = 14/2
y =7
now use the value of (y) in the equation (i)
2x+3y=18
2x+3(2)=18
2x+6=18
2x=18-6
2x=12
x=12/2
x=6
