Solve for ' x' and 'y' x + y = 3 2x + 5y = 12
O x=2 y=3
Ox=1.y=2
x + 2y
O x=2 y=5​

Answer 1

Answer:

x+y=3. equation 1

2x+5y=12. equation 2

Multiply first equation by 2

Now equation will be

2x+2y=6. equation 3

now subtract equation 2 and equation 3

3y=6

then y =2

and substitute value of y in equation 1 then

x+2=3

x=1

Hope you find the answer helpful
