Answer:
x = 1
Step-by-step explanation:
To find a solution to this by graphing, you would typically make a graph of the expression on the left, and another graph of the expression on the right. Where they intersect is the solution.
You would graph ...
- y = 2x
- y = -x +3
You're only interested in the x-value where these lines cross, x=1.
_____
<em>Alternate method</em>
Graph the difference of the left side and the right side:
y = (2x) -(-x +3)
and look for the value of x that makes y = 0. This, too, gives the solution x=1.
__
Of course, once you have the equation ...
0 = 3x -3
the solution is pretty obvious. (Divide by 3 to make it more obvious.)
