It sounds like you want to solve for x. If so, then follow these steps:
2x-1 = r
2x-1 = 4x ... replace r with 4x
2x-1-2x = 4x-2x ... subtract 2x from both sides
-1 = 2x
2x = -1
2x/2 = -1/2 .... divide both sides by 2
x = -1/2 is the fractional solution for x
x = -0.5 is the decimal solution for x.
--------------
If you want to figure out the value of r, then plug the x solution into the equation below and simplify
r = 4x
r = 4(-1/2)
r = -2
So the odds of getting a female or a male is 1/2. To make the odds of the number cube be 1/2, you need to divide the 6 sided die in half. the easiest way is to make even numbers represent a gender and odd numbers represent a gender.
Like terms would just be ones with the same variables
1. 7m, 20m, 5m
2. 13, 6, 2
3. 21bc, 8bc, 15bc
4. 27y, -6y, 9y
5. 45r, -7r, 5r
next section
6. 9r
7. 7r-8
8. -19r — 22p
9. 8r + 9p -7
10. 0
11. -19p — 2r
12. 9/4 r
13. 9r
14. 7/3p
ps. u should make questions that are long (like this) more points so ppl might be more willing to help (:
