b. If -3/5y = -5/3, then the value of y is _________

c. 8x - _____ = -21 has the solution -2.


Answer step by step....​

Answer 1

Answer:

a. 1/4+s/1=2/5

1+4s/4=2/5 ( by taking l.c.m)

5(1+4s)=8 ( by cross multiplication)

5+20s=8

20s=8-5

20s=3

s=3/20

b. -3/5y=-5/3

(by cross multiplication)

-9= -25y

(both the - symbol gets cancelled)

9=25y

y=9/25

c.please check the third question
