How to solve these, you divide the number multiplied by x by both sides.
1. Divide 2/3 by both sides, and you get y = 30.
2. Divide 0.2 by both sides, and you get x = -80
3. Divide 0.8 by both sides, and you get n = 2.5
4. Divide 3/4 by both sides, and you get m = 16
5. Divide -0.4 by both sides, and you get k = -70
6. Divide 3/5 by both sides, and you get h = -10
7. Divide -0.5 by both sides, and you get y = 40
8. Divide 3/5 by both sides, and you get x = 20
I hope this helped! For the fractions, just divide the fraction and divide by both sides with the decimal, and you will get the answer!
