Bisect means to cut something into two equal halves. This means that the two lengths are the same.

34.)
2x - 5 = 5x - 20

First isolate the variable. Add 5 to both sides:


2x = 5x - 15

Now subtract 5x from both sides:


-3x = -15

x = 5

35.)
5x + 4 = 2x + 7

-->
5x = 2x + 7 - 4

--->
5x = 2x + 3

---->
5x - 2x = 3

----->
3x = 3

So x = 1

Q34.

If BE is the bisector of AD then:

2x - 5 = 5x - 20 |+5

2x = 5x - 15 |-5x

-3x = -15 |:(-3)

x = 5

Q35.

If BE is the bisector of AD, then

5x + 4 = 2x + 7 |-4

5x = 2x + 3 |-2x

3x = 3 |:3

x = 1
