Step-by-step explanation:
Given sets are :
A = {1,2,3,4} and B = {a,b,c}
(i)
They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11
For this case we have, by definition:

So, we have:

On the other hand we have that by definition:

Thus, the expression can be written as:




So, we have:
