Answer 2

Answer 3

\[6-x-x=18\] rigtht?

Answer 4

Yes.

Answer 5

on planet earth most people write \(-x-x\) as (-2x\) so start with
\[6-2x=18\]

Answer 6

then subtract \(6\) from both sides
after that, divide both sides by \(-2\)

Answer 7

So it would be B ( 6) right?

Answer 8

Answer 9

What about the second question? @satellite73

Answer 10

4x - 3/5 = 2/5
4x-3/5+3/5 = 2/5+3/5 (adding both sides 3/5)
4x= 2/5+3/5
4x = 5/5
4x= 1
x= 1/4
