Question

Points A, B and C are collinear . Point B is between A andSolve for given the following

Answer 1

`x = 7`

Explanation:

Given

`AC = 3x +3`

`AB = -1+2x\\`

`BC =11`

Required

Find x

We have:

`AC = AB + BC`

So, we have:

`3x + 3 = -1 + 2x + 11`

Collect like terms

`3x - 2x = -1 + 11 - 3`

`x = 7`
