The solution is not a number, but a line. Graph it.
x - 3y = -9
standard form is y=mb+c so solve for y
-3y = -x + -9
y = (1/3)x + 3
This gives the slope of (1/3) and the y-intercept of 3.
All (x,y) coordinates along this line are solutions to the equation.■
You cannot solve one linear equation in two variables. You need two equations that are independent.
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
