Solve for the value of x in the diagram: Show your work and explain the steps you used to solve.

Since EB is parallel to CD, triangles ABE and ACD are similar. So, we can set up a proportion between correspondent sides:

Substituting values, we have

This implies

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
