Answer:

-88x + 10y

Step-by-step explanation:

-5x+3y= -93x+7y=23

we cannot do anything to numbers with unlike signs so we will do this

23=-5x+3y=-93x+7y

now we will take the numbers with like signs to one place like this

23=-5x+93x+3y+7y

now we can solve this

- x + = -

+ x+=+

-x-=-

23= 88x+10y ANSWER
