Question

Solve this equation: y + 3 = –y + 9

Answer 1

3

Explanation:

1. Regroup terms.

y+3=9−y

2. Subtract 33 from both sides.

y=9-y-3y=9−y−3

3. Simplify 9-y-39−y−3 to 6-y6−y.

y=6-yy=6−y

4. Add yy to both sides.

y+y=6y+y=6

5. Simplify y+yy+y to 2y2y.

2y=62y=6

6. Divide both sides by 22.

y = 6/2

7. Divide

y = 3
