subtract 2x from both sides
5xy=3-2x
devide both sides by 5x
y=(3-2x)/5x

5xy + 2x = 3
Try to isolate y
Subtract 2x from both sides: 5xy = 3 - 2x
Divide both sides by 5x: y = (3 - 2x) / 5x
Can be "simplified" further; The fraction on right can be broken up into two: 3/5x and -2/5
Final simplified result?
y = 3/5x - 2/5

5xy + 2x = 3
y is to be solved.
So we have to isolate 'y' to anyone of the sides.
5xy = 3 - 2x
(When the side changes '+' terms will become '-' terms.)
From the Left Hand Term, again '5x' is to be removed. Between 5x and y the sign is "multiplication" and when "5x" is brought to the Right Hand Side the sign will become "division"
y = (3-2x) / 5x
The denominator "5x" in the Right Hand Side is common to both the terms in the numerator.and it can be expanded.
y = 3/5x - 2x/5x
y = 3/5x - 2/5..........Ans.

5xy + 2x = 3
5xy = -2x + 3
y = -2x/5x + 3/5x
y = -2/5 + 3/5x

Hey there!
Here's the answer.
5xy+2x=3 --> Write the problem.
x(5y+2)=3 --> Factor out x in the left side of the equation.
5y+2=3/x --> Divide both sides by x.
5y=(3/x)-2 --> Subtract 2 on both sides of the equation.
y=((3/x)-2)/5 Divide both sides of the equation by 5.
Note that you can write the answer as (3/5x)-(2/5) or
(-2x+3)/5x.
So the answer is (-2x+3)/5x.
Hope it helps!

5xy + 2x = 3
5xy = 3 - 2x {subtract 2x from both sides}
y = (3 - 2x)/5x {divide by 5x}

subtract 2x from both sides
5xy = 3 - 2x
divide both sides by 5x
y = (3-2x)/ 5x

5xy + 2x = 3 :first thing you have to do is to subtract 3 by 2x
5xy = 3-2x :then, divide 3-2x by 5x to get the value of y.
(3-2x)/5x = y :put the parentheses in 3-2x, because of the
combining terms.
y = (3-2x)/5x :poof! you got the right answer.

5xy+2x=3
divide both sides by x
(5xy)/x=2x/x=3/x
5y+2=3/x
subtract 2 from both sides
5y=3/x - 2
divide by five
y = (3x-2)/5

5xy + 2x = 3
there's two variables, x and y in this equation, so you solve y in terms of x:
x(5y+2) = 3
5y+2 = 3/x
5y = 3/x - 2
y = (3/5x) - 2/5
