Given the set A=(2,5) and B=(5,7,9) find the following: AnB a
5
b
2.9
n
2,5,7,9
7,9
d

Greetings from Brasil

The intersection of two sets is given by the elements that are common - present in both - to the sets.

A = {2; 5}

B = {5; 7; 9}

Element in both sets = 5 So

yes yes yes yes yes yes yes yes yes

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
