jenniferjuice · Answer

it doesn't have 3

anonymous · Answer

i didn't finish it for you

anonymous · Answer

once you divide by -3, you have
x-2 = -3
solve for x

jenniferjuice · Answer

but wouldn't you have to use the distributive property?

@callie2240 HELP!

anonymous · Answer

You can do that, as well but it is easier just to divide by -5. You can do that because you times (x-2) by -5

jenniferjuice · Answer

yeah i got -5 but im not too sure it is right

anonymous · Answer

$$-5 * (x-2) = 15$$
$$\frac{ -5 * (x-2)  }{ -5 }= \frac{ 15  }{ -5 }$$
$$(x-2)+2=-3+2$$
$$x=-1$$

you can always dbl chk your results to determine if they are correct or not

anonymous · Answer

first distribute -5(x-2) that would be -5x+10=15 Now -10 on both sides -5x=5 Now divide by -5 which is x=-1 understand?

amistre64 · Answer

-5( x-2)    =  15

-5(-5-2)  ?=?  15

-5(-7)  ?=?  15

35  ?=?  15  , its not -5

anonymous · Answer

You can do it either my way, or callie's way. They both work, because the distributive property is a multiplicative property.
