The model represents an equation. What value of x makes the equation true?
a) 17/2
b) 17/6
c) -17/2
d) -17/6

Answer:
Option b) 17/6
Step-by-step explanation:
The equation is an algebraic equation:
This can be expressed as follows:
4x - 8 = -2x + 9
rearranging the terms:
4x + (+2x) = 9 +(+8)
6x = 17
x = 17/6
Hence option B.
This example represents what are known as directed numbers.
