5x=-3y-9

Question

2x-5y=-16

elimination

Answer 1

set into standard format

5x+3y = -9
2x-5y = -16

Now multiply by proper ratios to eliminate y:

25x+15y = -45
6x-15y = -48

now add to eliminate y:

31x = -93
x = -3

now substitute that value for x into either of the original equations to get y.
