2. something
OpenStudy (anonymous):

OpenStudy (anonymous):
2.5
OpenStudy (anonymous):
Yeah, 1, so you're canceling out the 2(x) by / 2
OpenStudy (anonymous):
so you have x + 1 after distributing that part

Do you understand that?
OpenStudy (anonymous):
yus kinda
OpenStudy (anonymous):
kinda lost o;

OpenStudy (anonymous):
lol i know that part

I just dont get how you mulitied 1/2 and 2
OpenStudy (anonymous):
1/2 = 0.5
0.5 * 2 = 1
OpenStudy (anonymous):
I see o;
OpenStudy (anonymous):
-1/4(3x-1) is the same.
OpenStudy (anonymous):
Although you'll have to use some fractions for this one.

isss it -7.5?
OpenStudy (anonymous):
for -1/4 times 3
OpenStudy (anonymous):

OpenStudy (anonymous):
Wait, it's just -3/4.
OpenStudy (anonymous):
So we have
-3/4 + -1/4
OpenStudy (anonymous):
-3/4 + -1/4 = -1

o:
OpenStudy (anonymous):
now what ;D
OpenStudy (anonymous):
x + 1 - 1 = 15
OpenStudy (anonymous):

OpenStudy (anonymous):
I just did, the fractions total at -1.

OpenStudy (anonymous):
oh o:
OpenStudy (anonymous):
so you have to solve for x.
x + 1 - 1 = 15
OpenStudy (anonymous):
hmm
OpenStudy (anonymous):
Combine like terms.
OpenStudy (anonymous):
it couldnt be 2 though o;

what is 1 minus 1?
OpenStudy (anonymous):
oh o_o 0
OpenStudy (anonymous):

but none of the answers is 15 o;
OpenStudy (anonymous):
i mean xD
