Question

2x+1/y=3 (for y)

Answer 1

If you mean (2x+1)/y=3

First, multiply both sides by y

2x+1=3y

To make as an expression equal to zero, then 2x+1-3y=0

Without another equation to use the substitution method, I cannot solve for both variables. What were they asking for?

Answer 2

If taken as written and not (2x+1)/y=3:

2x+1/y = 3

Multiply both sides by y

2xy+1 = 3y

2xy -3y = -1

y(2x-3) = -1

y = -1/(2x-3) x≠3/2
