Answer:
x=y+7
Step-by-step explanation:
−8x+3y−18=−7x+2y−25
Step 1: Add 7x to both sides.
−8x+3y−18+7x=−7x+2y−25+7x
−x+3y−18=2y−25
Step 2: Add -3y to both sides.
−x+3y−18+−3y=2y−25+−3y
−x−18=−y−25
Step 3: Add 18 to both sides.
−x−18+18=−y−25+18
−x=−y−7
Step 4: Divide both sides by -1.
−x
−1
=
−y−7
−1
