Question

4R-2/5=1-2R y 2-T/3=T/6= procedimiento

Answer 1

4 (R - 2/5) = 1 - 2R

4R -8/5 = 1 - 2R
4R+2R = 1 + 8/5
6R = 13/5
R = (13/5)/6
R = 13/30

2 - T/3 = T/6
2 = T/6 + T/3
2 = (T + 2T) / 6
2 = 3T/6
12 = 3T
T = 4

E. Ninguna de las anteriores

Answer 2

4R-2/5=1-2R           2-T/3=T/6
4R-2=5-10R            12-6T=3T
14R=7                     12=9T
R=1/2                       4/3=T
