Question

3x+2y=13 , 5x-2y=11​

Answer 1

Answer:

adding equation (1) and (2) .

we get,

8x=24

x=3

putting the value of x in equation (1)

Y=2

Answer 2

3x +2y=13......1)

5x-2y=11........2)

by elimination method

3x+2y=13

5x-2y=11

8x=24

x=24/8

x=3

putt in equation 1

3x+2y=13

3(3)+2y=13

9+2y=13

2y=13-9

2y=4

y=4/2

y=2

x=3& y=2
