Question

Multiple choice value of x

Answer 1

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

Answer 2

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
