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
