Specifically, we graphed the two equations y = 2x + 5 and y = (-3/2)x + 2, and
noted ... So, if y = -3x + 7 and y = 2x - 8, setting the y-values equal to each other (
the right ... 3 = x. So, we found that x = 3. What does that mean? Well, since we
are .... x = 5y in the second equation, then x must also equal 5y in the first
equation.
