Add ... –8 + –2. –3. –8. –10. 4. –3 – 24. 5. 10 – 17. 6. 13 – 9. = –3 + –24. = 10 + –17 ... 30. 5 + 4 x 3 = ____46_______. 12. (7)(9) +. 9. 3 – 20 x 3 = ____6______.
Step-by-step explanation:
7 = 10.2
12 = 17.7
Let's take
d = 17.7 - 10.2/ 12 - 7
d = 7.5/ 5
d = 1.5
The common difference is 1.5

We want to solve

Subtract 2/(2x+1) from each side.

Add 1/4 to each side, and simplify the left side.

Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1
Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2 or x = 4 1/2.
