The set is empty since there are no common elements
<h3>Set theory</h3>
Given the following sets
A={0,2,4,6,8} and B={-2,-4}
Required sets
A n B
Since intersection means that we are to write out all the values common to the set A and B, hence the equivalent set will be;
A n B = {}
The set is empty since there are no common elements

Answer:
10
Step-by-step explanation:
P.s. Coefficient always goes before the variable
= 2b + 4
= 2(3) + 4 Substitute b for 3
= 6 + 4
= 10
Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y.
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y.
We can set -3 = 3y-x or 1 = x-5y.
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.
We can do a bit of algebra which would get us x = 11.
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.
y=2
x=11, y=2
