Question #0db52

Answer 1

`x=9`

Explanation:

I believe some confusion exists here since `x` is used for two different things: the location of a point on a line segment and a variable used in defining the lengths of line segments.

Here is what I think is intended:

From the above we have:
`color(white)("XXX")(2x+13)+(7x-6) = (2x+70)`

`rarrcolor(white)("XXX")9x+7=2x+70`

`rarrcolor(white)("XXX")7x=63`

`rarrcolor(white)("XXX")x=9`
