Answer to Problem 7CYU
7 episodes
Explanation of Solution
Given information:
Sit com uses 0.3 gigabyte of memory, a drama uses 0.6 gigabyte, and a 0.6 gigabyte. And also downloaded 7 programs with a total memory of 3.6 gigabyte
Calculation:
Multiply the primary equation by -6 and the other equation with 10 so the two equations would have to be 6d and -6d
Here the first equation is multiplied by -6 and simplified
The second equation is multiplied by 10 and simplified
Now both the equations are added in order to find any of the variables
And then the following equation is obtained
Both the sides are divided by -3 and thus
Substituting the value of s in the equation value of d is obtained
Now substitute the 2 known values to the original equation to find the last unknowing variable
Now all the values are substituted in the following equation
Conclusion:
7 episodes
