How do you solve the system by graphing #x=3# and #3y=6-2x#?
This system is composed of two straight lines, and the solution is the point where the lines cross. In this case,
These two equations are the equations of straight lines. The line
The other equation is not in standard form for a line. We don't actually need it to be to solve the system, but I'll just include it here so that it's clear it's the equation of a line:
To solve, we know that the
The solution, then, is that the lines cross at the point
