5x-d/6 =2x
a. d= 7/6x
b. d = 7x
c. d = – 7x
d. d= -7/6x

Woops
\[\large 5x - \frac{d}{6} = 2x\]
Like that?
OpenStudy (anonymous):
um. i think
OpenStudy (johnweldon1993):
Nope I tried it like that and it doesn't work lol
OpenStudy (johnweldon1993):
So I'm actually going to assume it is
\[\large \frac{5x - d}{6} = 2x\]

what are you trying to do

solve the equation for D
OpenStudy (johnweldon1993):
So you would multiply both sides by 6
\[\large 5x - d = 12x\]
Now subtract 5x from both sides of the equation
\[\large -d = 7x\]
And finally divide both sides by '-'
\[\large d = -7x\]
OpenStudy (dmb1215):
ok
OpenStudy (dmb1215):
wait a sec wouldnt you multiply the 5x to both sides to get rid of 5x by the d
OpenStudy (johnweldon1993):
At what part? @Dmb1215

the first part 5x-d/6=2x
-d/6=2x*5x
OpenStudy (johnweldon1993):
No...so we have
\[\large \frac{5x - d}{6} = 2x\]
The first thing you need to do is get rid of that fraction...because you cannot do anything with a fraction on 1 side...
That is why I multiplied by 6...it cancels out the fraction...
\[\large 5x - d = 12x \]
Them it's just combining like terms....
