Answer:

  • [tex]\sf x=-3[/tex]

Step-by-step explanation:

CD + DB = CB

CD = x +10

CB = 8

[tex]\sf (x+10)+(x+4)=8[/tex]

[tex]\sf x+10+x+4=8[/tex]

Combine like terms.

  • [tex]\sf x+x+10+4=8[/tex]
  • [tex]\sf 2x+14=8[/tex]

Subtract 14 from both sides.

  • [tex]\sf 2x+14-14=8-14[/tex]
  • [tex]\sf 2x=-6[/tex]

Divide both sides by 2.

  • [tex]\sf \cfrac{2x}{2}=\cfrac{-6}{2}[/tex]
  • [tex]\sf x=-3[/tex]
