Question

solve the system of equations -2x+15y=-24 and 2x+9y=24​

Answer 1

-2x + 15y = -24
2x + 9y = 24.

On adding, we get....
24y = 0. Therefore y = 0.

Since y = 0, 2x + 0 = 24.
Hence x = 12.

Answer 2

Answer:

x=3

y=2

Step-by-step explanation:

-2x+15y=-24

+

2x+09y= 24

0x+ 24y= 48

=> 24y=48

=> y. =48÷24

=> y=2

therefore, 2x+9y=24

=> 2x+9X2=24

=> 2x+18=24

=> 2x=24-18

=> 2x=6

=> x=6÷2

=> x=3
