How do I solve for y in this equation? 3xy-28=16x

Answers

The value of y is 16/3 + 28/3x

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S

Given:

3xy-28=16x

3xy= 16x + 28

y = 16x/ 3x + 28/3x

y= 16/3 + 28/3x

$3xy-28=16x$

$3xy=16x+28$ $Add \ 28 \ to \ both \ sides$

$xy= (16x+28)/(3)$ $Divide \ both \ sides \ by \ 3$

$xy= (4(4x+7))/(3)$ $Factor \ out \ the \ common \ term \ 4$

$y= (4(4x+7))/(3x)$ $Divide \ both \ sides \ by \ x$
