Sets are equal if they have exactly the same elements B = (5,3,1)
B=A
The number of elements of set A is given n(A) n(A) = 3
The empty set is a set with no numbers
The universal set contains all the elements being discussed in a {{

Simultaneous equations
· Solve these simultaneous equations and find the values
of x and y.
· Equation 1: 2x + y = 7
· Equation 2: 3x - y = 8
· Add the two equations to eliminate the ys:
· 2x + y = 7
· 3x - y = 8
· ------------
· 5x = 15
· x=3
· Now you can put x = 3 in either of the equations.…read more
