Answer:
[tex]\boxed{\bf x=7}[/tex]
[tex]\boxed{\bf GH= 52}[/tex]
Step-by-step explanation:
In the line segment..
[tex]\bf 7x+3+3x-5=9x+5[/tex]
Combine like terms.
- [tex]\bf 10x-2=9x+5[/tex]
Add -2 to both sides.
- [tex]\bf 10x-2+2=9x+5+2[/tex]
Subtract 9x from both sides.
- [tex]\bf 10x-9x=9x+7-9x[/tex]
- [tex]\boxed{\bf x=7}[/tex]
[tex]\bf GH=7x+3[/tex]
- [tex]\boxed{\bf 52}[/tex]
