3y-1+2x-28=180 i need help making two equations out of this
Your question makes no sense
you have given us one equation with two variables.
This reduces to 2x - 3y = 209, which when graphed represents a straight line.
There are an infinite number of solutions, (points on the line), to this equation.
Dr Russ already told you that you would need two equations to have a unique solution.
