Find the value of y.

y = 2

Step-by-step explanation:

20y - 21 = 10y - 1

20y = 10y + 20

10y = 20

y = 2

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

1/3 + 1/5 = 8/15.
