Answer:
x=2
AB=3
Step-by-step explanation:
Set this 2 equations equal to each other to find x Sind the sides equal each other
[tex]2x-1=\frac{x+7}{3}[/tex]
Multiply 3 on both sides
[tex]6x-3=x+7[/tex]
Subtract x on both sides
[tex]5x-3=7[/tex]
Add 3 to both sides
[tex]5x=10[/tex]
Divide both sides by 5
[tex]x=2[/tex]
Now fil in x
2(2)-1
4-1
3
