How do you solve the system by graphing #x=3# and #3y=6-2x#?
1 Answer
This system is composed of two straight lines, and the solution is the point where the lines cross. In this case,
Explanation:
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
