Some Basics of Solving Equation :
A linear equation always represent a straight line in a graph.
Solving a pair of linear equation and finding x and y means (x, y) is the point of intersection of the two lines.
So you need to have 2 linear equations t find (x,y) the point of intersection

This is an equation for a line.
Let x = 0, then y = -5
The point (0, -5) is the y-intercept.
Let x = 2, then y = 3(2) - 5 = 6 - 5 = 1.
A second point is (2, 1).
Connect the dots.

You can't solve an equation with 2 variables. You can graph the solution as a line with slope = 3 and y-intercept = -5. Or if you have 2 equations, you can find the common solution through a variety of methods.

Again do you want to solve for x or what?
X = (Y +5)/3.

y = 3x -5,
y +5 = 3x
3x = y+ 5
x = (y + 5)/3 [answer].

it is solved as far as it gets
you need to give us what you are solving for and the vaules of something
Is it a line do you need slope and intercept?
Are you looking for x?
then its (y+5)/3
IS there more to the question?
