Answer:

The first equation should be multiplied by - 7 and the second equation by 3

Step-by-step explanation:

Indeed, let s multiply the first equation by -7

-7*9x-7*3y=7*18

and the second one by 3

3*8x+3*7y=3*10

when we add both the terms in y will be -7*3y+3*7y= 0

and then we can solve on x
