Y=3xy-1, Solve for y

Ket [755]

Answer:

y = $\frac{1}{3x-1}$

Step-by-step explanation:

Given

y = 3xy - 1

Collect terms in y on the left side by subtracting 3xy from both sides

y - 3xy = - 1 ← factor out y on the left side

y(1 - 3x) = - 1 ( divide both sides by 1 - 3x

y = $\frac{-1}{1-3x}$ ← multiply numerator/denominator by - 1

y = $\frac{1}{3x-1}$
