Question

Rewrite the equation to isolate the variable
y=9x+2
and
df=g-10

bahrom7893 · Answer

isolate which variable?

anonymous · Answer

oh im sorry , for the first one its for x and the second one for d

bahrom7893 · Answer

1) subtract 2 from both sides:
y-2 = 9x +2 -2
y-2 = 9x
2) divide both sides by 9:
(y-2)/9 = 9x/9
(y-2)/9=x

Do the 2nd one yourself. I'll help you if you're stuck.

anonymous · Answer

okay..im coming let me try to solve it.

anonymous · Answer

so first I subtracted 10 from both sides... 
df=g-10
+10   +10
 
the 10s cancel out... then that leaves me with df=g ... I think ? am I doing it right so far?

bahrom7893 · Answer

wait wrong

anonymous · Answer

no , I add 10 to both sides..

bahrom7893 · Answer

you want to isolate d

bahrom7893 · Answer

so you just need to perform the operations that will clean up the side that d is on

anonymous · Answer

so , don't add 10

anonymous · Answer

?

bahrom7893 · Answer

no, divide both sides by f

anonymous · Answer

okay so then , d=g-10/f ?

bahrom7893 · Answer

well yea but it would be: (g-10)/f

anonymous · Answer
