Question

Write a real world situation that could be modeled by the equation 30x=48+22x

Answer 1

30x+48=22x

Subtract 22x from both sides:

30x+48-22x=22~x-22x

Group like terms:

30x-22x+48=22x-22x

Simplify the arithmetic:

8x+48=22x-22x

Simplify the arithmetic:

8x+48=0x

Simplify the right side:

8x+48=0

so the answer is -6

Answer 2

For this case we have the following equation:
30x = 48 + 22x
An example of real life is:
"Laura earns $ 30 per hour at her job, Maria earns 22 dollars per hour at her job plus 48 $ of fixed salary, find the number of hours for which both get the same profit"
In the given equation,
x: represents the time in hours.
