Question

B is the midpoint of AC. AB=2x+4; BC=5x-11. Find X

Answer 1

x=5

Explanation:

Since B is the midpoint you would need to form the equation like this:

`2x+4=5x-11\\-2x+11 -2x+11\\15=3x\\x=5`

Answer 2

x=5

Explanation:

AB and BC must be equal if B is a midpoint

Therefore

2x+4=5x-11

Simplify:

add 11 to both sides=

2x+15=5x

subtract 2x both sides:

3x=15

Divide

x=5
