Answer:


  • \sf x=-3

Explanation:

CD + DB = CB

CD = x +10

CB = 8


\sf (x+10)+(x+4)=8


\sf x+10+x+4=8

Combine like terms.


  • \sf x+x+10+4=8

  • \sf 2x+14=8

Subtract 14 from both sides.


  • \sf 2x+14-14=8-14

  • \sf 2x=-6

Divide both sides by 2.


  • \sf \cfrac{2x}{2}=\cfrac{-6}{2}

  • \sf x=-3
