Homework Help: algebra

Can someone show me the step to solving this equation because I am just not getting it. My teacher is confusing me, so I need someone else to explain it in a different uncomplicated way. y-1/x+3 = -3/4.Thanks so much you guys for the help.

You must use parentheses when typing equations like this; otherwise we can't be sure what the problem is.

Is the equation
(y-1)/(x+3) = -3/4, or
y - (1/x) + 3 = -3/4 ?
Those are two entirely different equations.

If it is the former, get rid of the denominator to write
y - 1 = -3x/4 -9/4

Then combine the constants on one side.
y = -3x/4 -5/4

You cannot solve a single equation for two unknowns. Do they want an equation for y in terms of x, or vice versa?
