Answer:

14.x=-2

21. x=-2

23. x=5

7.x=12

2.x=49

Explanation:

I got your back bro:

14. Subtract 7 on both sides. Then divide -16 by 8. x=-2

21. Add 1 on both sides. Divide 18 by -9. x=-2

23. Subtract 24 on both sides, then divide -25 by -5. your answer is x=5.

7. Add 2/5 on both sides. then multiply 2 2/5 by the reciprocal of -1/5. Your answer is x=12

2. Subtract 5 on both sides. Multiply 14 by the reciprocal of 2/7, or 7/2. Your answer is 49.

Good luck!
