To solve this problem, we will setup a system.
We know that two numbers have a sum of 12 and a difference of 4.
So let's call our first number x and our second number y.
So we know that x + y = 12.
We can also say that x - y = 4.
Now rewrite the equations on top of each other.
<h2>x + y = 12</h2><h2>x - y = 4</h2><h2 />
Now we can use addition to solve this system.
When we add the equations together, the y's will cancel.
So we have 2x = 16.
Now divide both sides by 2 and x = 8.
Now plug an 8 back in for x in the first equation to find that y = 4.
So our numbers are 8 and 4.
The minutes remaining till the end of the month = 500 - 310 = 190 minutes
now to split these minutes equally, we will divide them by 7 days of week
daily usage = 190/7 = 27.14 minutes
since we can not talk for 0.14 minutes, therefore,to equally split the remaining minutes, you should speak 27 minutes per day with one extra minutes remaining to be used on the day you choose
300 is the answer. Hope I helped :)
