Let's solve for x.-------------------------------------------------
x−y=−3------------------------------------------------
Step 1: Add y to both sides.x−y+y=−3+yx=y−3-------------------------------------------------
Answer:-------------------------------------------------
x=y−3
-------------------------------------------------
and
-------------------------------------------------
Let's solve for x.x+3y=5------------------------------------------------
Step 1: Add -3y to both sides.x+3y+−3y=5+−3yx=−3y+5-------------------------------------------------
Answer:x=−3y+5
