Question

Using the following image solve for x

Answer 1

Answer:

x = -3

Step-by-step explanation:

x + 10 + x + 4 = 8

2x + 14 = 8

2x = -6

x = -3

Check:

2x + 14 = 8

2(-3) + 14 =8

-6 + 14 = 8

8 = 8

Answer 2

Answer:

• $\sf x=-3$

Step-by-step 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.

• $\sf \cfrac{2x}{2}=\cfrac{-6}{2}$

• $\sf x=-3$
