Question

solve: 2x - 3y = 9 ; 2x + y = 13​

Answer 1

Answer:

$2x - 3y = 9 \\ 2x + y = 13 \\( 2x + 2x) - (3y - y) = 13 + 9 \\ 4x - 2y = 22 \\ x - y = \frac{22}{2 \times 4} \\ x - y = \frac{11}{4}$

Answer 2

Answer:

I hope u got it.

Step-by-step explanation:

2x-3y=9

2x=9+3y

2x+3y=13

9+3y+y=13

9+4y=13

4y=13-9

4y=4

y=1

2x-3y=9

2x-3×1=9

2x-3=9

2x=9+3

2x=12

x=6. in this equation x =3

2x+3y=13

2x+3×1=13

2x+3=13

2x=13-3

2x=10

x=5. in this equation x=5

in whole equation y=1.
