Find the value of x if a, b, and c are collinear points and b is between a and c.
ab=12,bc=5x−2,ac=3x+20
a. 2
b. 7
c. 6
d. 5

D. 5

Step-by-step explanation:

AC = AB + BC

Substituting what we know

3x+20 = 12 + 5x-2

Combining like terms

3x+20 = 10 +5x

Subtract 3x from each side

3x+20-3x = 10 +5x-3x

20 = 10+2x

Subtract 10 from each side

20-10 = 10-10 +2x

10 = 2x

Divide by 2

10/2 =2x/2
