Distribute the negative like x-12+x=38
like terms 2x-12=38
My math teacher wants us to show each step and Im confused
add 12 to both sides: 2x=38+12
then you divide
Now divide both sides by 2: x=50/2=25
That's all. You not confused about any of the steps?
Actually i am
Where do you get stuck?
So you know subtraction can be turned into addition right?
but isnt it distributive property
So we have 12+-(12-x)=38
that - in front of that paranthesis can be read at -1
so what is -1(12-x)?
Huh??!!! you totaly confused
the changing subtraction to addition?
because for example she said to do multiplication during distributive property 3(12+9)
yes so what is -1(12-x)
yes which =-12+x
now we have x+(-12+x)=38
why do you have to change the sub sign
since addition is commutative and associative we have x+x-12=38
cant you just put 12x?
so we have 2x-12=38
then i know
+12 on both sides giving us 2x=50 then divide both sides by 2
ohhhhhh i get it!!
i <3 you thankyou!!!!!!!11
have an awesome day
i finished it? That's all you needed? lol
ok no worries lets just find your mistake
