Question

x+2y = 3
3x - 2y = 7

Answer 1

x+2y=3×3

3x+6y=9

3x-2y=7

- + -

_________

0 +8y=2

y=2/8

put in any of the eq.

3x-2×2/8=7

3x-4/8=7

24x-4=7

_________

8

24x-4=54

24x=54+4

24x=60

x=60/24

Answer 2

Answer:

It can be

By using elimination method...

Step-by-step explanation:

X+2y=3

3x-2y=7

2y-2y cancelled

3x+x=4x

7+3=10

It will be

4x=10

X =10/4

X=5/2

Putting value of x in any one of the equation :-

X+2y=3

5/2+2y=3

5+4y=6

4y = 6-5

4y = 1

Y=1/4

Here is your answer

X=5/2

Y=1/4
