Answer 4

I don't know this mr steve hawking i thought to combine like terms as 3-21-7x=-4 which becomes -18-7x=-4 than +18 added to each sides getting -7x=14 than +7 times both sides or -7 times both sides?

Answer 5

wait i got this only way to cancle out -7x is to times both sides with -7 leaving x

Answer 6

wait,you made a mistake!

Answer 7

-18 - 7x = -4 --> +18 - 18 - 7x = -4 + 18 --> -7x = 14 --> x = -2
