Add 2x to both sides of the equation:
y - 2x = 3
y - 2x + 2x = 2x + 3
y = 2x + 3

Simple. this question only invovles one step, which is isolating "Y". If you add 2x to both sides of the equation then the y will be by itself. " y - 2x +2x = 3 + 2x ". The positive(+) 2x and the negative(-) 2x cancel out and your left with just y on that side. to finish off, rewrite the equation in slope-intercept form (y=mx+b)
"y = 2x + 3" and your done.

There's only one step.
Just add 2x to both sides of the equation.
Thus, y = 3 + 2x.

y=2x+3; y is on one side of the equal sign so naturally 2x+3 is what y =

Are you graphing this problem? You could make x anything you want. x is your independant variable, y can be your dependant meaning replace x with any number then solve to get y.
If you make x=1 you then have y-(2*1)=3
y-2=3
.+2.+2
--------
y=5
Check it like this
y-2x=3
5-(2*1)=3
5-2=3
One solution is (1,5)

yo can never solve one equation in two unknowns unless you get y interms of x
y = 2x +3 and it has infinite number of solutions every times you sub x by value you get a corresponding value of y

lol it cant be solved
the answer will be in terms of x
which is .. y = 2x + 3 !!
