Answer:
Step-by-step explanation:
So, to go about your question, we must first ask, how many hours a week is being worked?
In this problem, that is 9 hours per week.
Next, we must question how much per week is made
That is $92 per week
Finally, we must determine if the allowance is occuring many times in the week or just once.
In this problem, that is only occuring once for the week.
So, the equation we must setup is 9x +20 =92.
To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.
9x+20=92
-20 -20
Now our equation is
9x=72
Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.
<u>9x</u>=<u>72</u>
9 9
x=8 because of 72/9 is equal to 8.
I hope this helps, and I will answer any questions you have.
