If your equation is \frac{x}{-9} = -7, the only thing you need to do to get x by itself is to get rid of the denominator, the -9.  To get rid of a denominator, you multiply both sides by it, so you're left with 

x=-9*-7 so x=63

3x+5y=-3 x-5y=-5 show your work
frez [133]
We are given the equations 3x+5y=-3 and x-5y=-5.

Both equations have a 5y  term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.

3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8

The y terms cancel out since one is positive and one is negative. Now we can solve for x.

4x = -8

\frac{4x}{(4)} = \frac{-8}{(4)}

x = -2

Now plug -2 in for x in one of the original equations to find y.

(-2) - 5y = -5

-5y = -3

y = 3/5

Our answer as an ordered pair is (2, 3/5)

Solve for x in terms of a, b, and c: ax − 3b = c
expeople1 [14]
Add 3b to both sides and divide by a to isolate x.
ax - 3b = c
ax = c + 3b
x = c +3b / a

Good Luck Studying :)
