Look at the problem and work shown. in which line was an error made and what should have been done differently? six less than 4 times a number is 50. what is the number? 6 – 4n = 50 (line 1) 6 – 6 – 4n = 50 – 6 (line 2) –4n = 44 (line 3) –4n÷ –4 = 44÷ –4 (line 4) n = –11 (line 5)

were is the equation

3

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!
