Vanessa will graph the lines $$y = \frac{1}{3}x + 7$$ and $$y = 2x+5$$. What is the sum of the x-coordinates of the two lines' x-intercepts? Express your answer as a decimal to the nearest tenth.

To find the x interept, plug in the value 0 for y in both equations.

y=1/3x+7

0=1/3x+7

1/3x=-7

x=-21

y=2x+5

0=2x+5

2x=-5

x=-5/2
