Question

I already know the solution, but how did the expression get simplified?
n - 4 + 5n = 20

Answer 1

Start by combining like terms
5n+n=?

Answer 2

6n

Answer 3

Good
6n−4=20
add 4 to both sides
20+4=?

Answer 4

so, do I start by subtracting n from both sides?

Answer 5

* adding

Answer 6

Not quite we should always look for things we can combine it won't always be adding when dealing with negative numbers or subtraction signs you'll subtract

Answer 7

Oh!! We're adding like terms, I see now.

Answer 8

Yes! :-)
Ok Good
6n−4=20
add 4 to both sides
20+4=?

Answer 9

24 then will we divide by 6 from both sides

Answer 10

on*

Answer 11

Yes perfect :)

Answer 12

which = 4 !! :) Thank you!! :)

Answer 13

the -4 on the left and the 20 on the right are "like terms" in that they're both constants.
Adding 4 to both sides of your equation results in 6n = What?
