Question

solve
x+3y=7, 2x-3y=12​

Answer 1

Answer:

x=19/3

y=2/9

Step-by-step explanation:

Let us consider the first equation

x+3y=7

x=7-3y

Now let us substitute this value of x in the second equation

2x-3y=12

2(7-3y)-3y=12

14-6y-3y=12

9y=2

y=2/9

Now as x=7-3y = 7-3(2/9) = 7-(2/3) = 19/3

So, x=19/3 y=2/9
