Question

If DG = 10, what is the value of x?

Answer 1

Explanation:

(x+1) + (2x-15) = 10

x + 1 + 2x - 15 = 10

3x - 14 = 10

3x = 14 + 10

3x = 24

x = 24/3

x = 8

Therefore,

Option B is correct ✔.

Answer 2

The total length of the line is 10.

The line is divided by 2 equations. Add the two equations together to equal the total length:

x + 1 + 2x -15 = 10

Combine like terms:

3x -14 = 10

Add 14 to both sides:

3x = 24

Divide both sides by 3:

x = 24/3

x = 8

The answer is B. 8
