Question

Check graphically whether the pair of equations

2x + 3y = 6

2x - 3y = 12​

Answer 1

Answer:

2x +2x +3y -3y = 6+12

4x = 18.

x = 4.5

2x+3y =6

9+3y =6

3y = -3

y = -1

Answer 2

Answer:

2x + 3y = 6

2x - 3y = 12

Step-by-step explanation:

2x + 3y = 6

- 2x - 3y = 12

= 6y = 18

= y = 18 / 6

= y = 3

put y = 3 in equation.........( 1 )

= 2x - 3y = 12

= 2x - 3( 3 )= 12

= 2x - 9 = 12

= 2x = 12 - 9

= 2x = 3

= x = 3/2

= x = 1.5

.......then we got ( x = 1.5 ) , and ( y = 3 )
