Answer 2

not exactly sure what you're asking

Answer 3

do you want to move that A on the right side over to the left side?

Answer 4

likef or example a+w+t=90 i would like to get the first equation similar like for example a+w+t=20

Answer 5

yes

Answer 6

we have A+20 on the right side

or

20+A

Answer 7

to undo that +A, we have to subtract A from both sides

Answer 8

that will give us

W +T=A+20

W +T-A=A+20-A

W +T-A=20

and you can rearrange terms to get

-A+W+T = 20
