Este tambien ayuda por favor

Answer 1

Explicación paso a paso:

2y/3 +3+y/2=2/5-4y/5-4

7y/4+4y/5= - 33/5

51y/20=-33/5

Y=44/17

Answer 2

Explicación paso a paso:

(1 /3). (2.y+1) + y/2 = (2/5) . (1-2.y) - 4

2.y/3 + 1/3 + y/2 = 2/5 - 4.y/5 - 4

2.y/3 + y/2 + 4.y/5 = 2/5 - 4 - 1/3

[ 2.y.(10) + y.(15) + 4.y.(6) ]/30 = [ 2.(3) - 4.(15) - 1.(5)]/15

49.y/30 = -59/15

y = - 59. 2 / 49

y = -118/49
