Hello world and welcome to another funza Academy fun Math video.
Todays problem involves finding values of 4 unknowns.
So here is the problem?
In this figure, we have 4 result values - 13, 8 , another 8 and 6.
And we have 4 unknowns - say, a, b, c and d.
We know certain operations between the unknowns that give us the result values.
For example:
a + b is equal to 8
a + c is equal to 13
b + d is equal to 8
and finally
c - d = 6
Based on this information, can you find the values, of a, b , c and d.
Please pause the video and give the problem a try
