Question

3x-(2+6x) less than or equal to 28
i keep getting 10/3? did i do something wrong?

Answer 1

-3x<=30
x<=30/-3
x<=-10
is what I got

Answer 2

does that make sense?

Answer 3

to you?

Answer 4

um no

Answer 5

\[3x-2-6x\]
\[-3x-2\]

Answer 6

can you see that now?

Answer 7

that's the leftside of your equation.
add 2 to both sides.
and then divide both sides by -3
then you will get -10 as your answer

Answer 8

ut wouldn't u add -6x to -6x and 3x?

Answer 9

i mean add 6x

Answer 10

when you see -(2+6x)
this means you distribute the negative to both terms
so -2-6x is what it looks like with the brackets removed
so you have +3x and -6x
when you add those 2 terms you get -3x

Answer 11

ohhh ok

Answer 12

3x-(2+6x)<or equal to 28.
=> 3x-2-6x<or equal to 28.
=> -3x-2< or equal to 28.
=> 3x+2> or equal to 28. (Note the change in sign).
3x>or equal to 26
Therefore x is > or equal to 26/3.
This is what I got. -__-

be careful with the <> symbol.
