Answer:

[tex]x = 7[/tex]

Step-by-step explanation:

Given

[tex]AC = 3x +3[/tex]

[tex]AB = -1+2x\\[/tex]

[tex]BC =11[/tex]

Required

Find x

We have:

[tex]AC = AB + BC[/tex]

So, we have:

[tex]3x + 3 = -1 + 2x + 11[/tex]

Collect like terms

[tex]3x - 2x = -1 + 11 - 3[/tex]

[tex]x = 7[/tex]
