Question

find the value of x+y without solving for x and y 3x-2y=5;3y-2x=3


​

Answer 1

Answer:

x+y=2

Step-by-step explanation:

3x−2y=5............ (1)

3y−2x=3

−2x+3y=3

Multiply (1) by 2 & eq (2) by 3=33

6x−4y=10..........(3)−6x+9y=19..........(4)_______________Adding eqn (3) and (4), we get

6x−4y=10−6x+9y=19___________5y=1

y=51​

Putting the value in

6x−54​=10

6x=10+54​=554​

x=5×654​=59​

x=59​

Now x+y=59​+51​=510​=2$$

x+y=2
