Question

3(2r-5)/5=3r-6/4 cual sera el resultado

Answer 1

3(2r-5)/5=3r-6/4
entonces
(6r-15)/5=3r-6/4
(6r-15)=5(3r-6/4)
6r-15=15r-15/2
6r-15r=-15/2+15
-9r=15/2
r=15/2/-9/1
r=5/-6 R/
bien ahi esta espero te ayude 

Answer 2

2(2r-5)/5=3r-2x3/2^2
2(2r-5)/5=3r-3/2^2-1
2(2r-5)/5=2(3r)+(-3)/2
2(2r-5)/5=6r-3/2
2x2(2r-5)=5(6r-3)
4(2r-5)=5(6r-3)
4x2r-4x5=5x6r-5x3
8r-20=30r-15
-22r=5
22r/22=-5/22
r=-5/22
