Please solve this problem if u are brainliest

Step-by-step explanation:

2. 3x-1/3 = 5

+1/3    +1/3

-

3x= 5   1/3

÷3     ÷3

x=1.77777777778

5.  3x-9=5x-3

+3     +3

-

3x-6=5x

-3x    -3x

-

-6=2x

÷2    ÷2

-

-3=x

8.   3x-2x=8  ( I crossed multiplied btw)

x=8

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
