Let's use the variable x to represent the unknown number.
Then the "quotient of a number and 2" would be represented by: x
2
"Eight more than" this quotient would be represented by: x + 8
2
Also, "is 6 " would be represented by: = 6
Combining these expressions gives us: x + 8 = 6
2
Now use inverse operations to find the value of x:
x + 8 = 6
2
x + 8 - 8 = 6 - 8
2
x = -2
2
x * 2 = -2 * 2
2
x = -4
