Question

2r-(5-r)=13+2r

Answer 1

2r -(5 - r) = 13 + 2r -- distribute through the parenthesis
2r - 5 + r = 13 + 2r -- combine like terms
3r - 5 = 13 + 2r -- subtract 2r from both sides
3r - 2r - 5 = 13 -- add 5 to both sides
3r - 2r = 13 + 5 -- combine like terms
r = 18

check...
2r -(5 - r) = 13 + 2r
2(18) - (5 - 18) = 13 + 2(18)
32 -(-13) = 13 + 32
32 + 13 = 13 + 32
45 = 45 (correct)

r = 18

any questions ?

Answer 2

2(18) - (5 - 18) = 13 + 2(18)
36 -(-13) = 13 + 36
36 + 13 = 13 + 36
49 = 49 (correct)

r = 18
