Question

solve the equation and explain your steps?
2 r – 8 + 5 r = 10 + r

Answer 1

2r-8+5r=10+r
(add like terms)=> 7r-8=10+r
6r=18 >>> 18/6
r=3
Make sense?

Answer 2

\[2r-8+5r=10+r\\7r-8=10+r\\6r-8=10\\6r=18\\r=3\]1. Combine like terms, so 2r + 5r = 7r.
2. Subtract r from both sides, so 7r - r = 6r.
3. Add 8 to both sides to isolate 6r.
4. Divide both sides by 6 to find r.

Answer 3

thank you guys :)
