Answer:

x = 12

consider this a straight line:

A                        B                          C

-------------------------------------------------

solve for AB:

⇒ AB = AC - BC

⇒ AB = 2x - 7 - ( x - 3 )

⇒ AB = 2x - x - 7 + 3

⇒ AB = x - 4

  • given AB = 8

solve for x:

⇒ x - 4 = 8

⇒ x = 8 + 4

⇒ x = 12

☆solve for AB:

→ AB = AC - BC

→ AB = 2x - 7-(x-3)

→ AB = 2x - x - 7+3

→ AB = x - 4

given, AB = 8

☆solve for x:

→ x - 4 = 8

→ x = 8 + 4

→ x = 12
