Step-by-step explanation:
Did it on khan a few months ago
sorry if I made it wrong, my memory isn't too well right now
We have similar triangles so
12/x = (12+78)/(x+13)
We can skip some algebra by doing the ratio on the pieces. We'll show it works at the end.
12/x = 78/13
x = 12(13)/78 = 2
We check
12/2 = 6
(12+78)/(2+13) = 90/15 = 6, good
Answer: x=2

Step-by-step explanation:
if your getting confused, just imagine a number line in your head or write one on your paper, that has negative numbers on the left side and positive numbers on the right side
(ex: ....-3, -2, -1, 0, 1, 2, 3....)
remember that the number that is in the left side is always less than the the number on the right side, meaning the number on the right side of the number line is greater than the number on the left side.
