Vanessa will graph the lines y = 1/3x + 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.

you couls mathematically solve them, or just use desmos
for $y = \frac{1}{3}x + 7$ the x value is $-21$ and for $ y = 2x+5$ the x value is $-2.5$
*What is the sum of the x-coordinates of the two lines' x-intercepts?*
$-21+-2.5=\boxed{-23.5}$
+37159 At the x axis intercepts, the value of y = 0
First one: 0 = 1/3x + 7 x = -21
Second one : 0 = 2x+5 x = - 5/2 sum = - 23 1/2
