Answer:

Step-by-step explanation:

Question 1

5x+2y=21

5x+2y+−2y=21+−2y

5x=−2y+21

Step 2: Divide both sides by 5

5x/5=-2y+21/5

Answer =-2/5 y+21/5

– 2x+6y=-34

Question 2

−2x+6y=−34

Step 1: Add -6y to both sides.

−2x+6y+−6y=−34+−6y

−2x=−6y−34

Step 2: Divide both sides by -2.

-2x/-2=-6y=-34/2

x=3y+17
