Answer 2

Explanation:

Solve it by elemination method

3x+5y=12

3x-5y=18

(-) (+). (-) sign will change

3x gets cancelled

5y+5y = 10y

12-18= -6

10y = -6

y = -6/10

y = -3/5

Now substitute y value in equation

3x+5y=12

3x+5(-3/5)=12

3x-15=12

3x=12+15

3x=27

x=27/3

x = 9

Therefore x = 9 and y = -3/5
