Question

R+8-5r=2(4-2r) what is r

Answer 1

To solve the equation R+8-5r=2(4-2r) for r, distribute 2, combine like terms, and isolate r to find r=R.

Step-by-step explanation:

To solve the equation R+8-5r=2(4-2r) for r, we will follow these steps:

1. Distribute 2 to both terms inside the parentheses:
   R + 8 - 5r = 8 - 4r
2. Combine like terms on both sides of the equation:
   R - 5r + 4r = 8 - 8
   R - r = 0
3. Add r to both sides of the equation to isolate r:
   R - r + r = 0 + r
   R = r

Therefore, the value of r is R.
