What s the value of x?

See the attachment for the problem to be answered.

Answer 1

The answer is x=4
the bigger triable is 5 times bigger than the smaller triangle therefore you multiply 4 by 5 which gives you 20 which means 3x+8 equals 20
to find x steps:
3x+8=20
-8. -8
3x=12
x=4

Answer 2

Answer: x=4

Step-by-step explanation: as you saw everything is multiplied by 5 this means the 4 became a 20.

3x+8=20

-8 on both sides

3x=12

divide both sides by 3

x=4
