Hi Jessica,
 
Here you go ~
 
y = (x * .4175) + x
 
Substituting y and rewriting -
 
874.90 = .4175x + x
 
874.90 = .4175x + 1x
 
874.90 = 1.4175x
 
Now, let's rewrite the equation again and solve for x -
 
x = 874.90/1.4175
 
x = 617.21
 
I hope this helps!

Rewrite the equation as y = x*(0.4175+1)
y = 1.4175*x
x = y/1.4175
x = 874.9/1.4175 = 617.2134
y = [x*(0.4175)] = x
 
y = 874.90 = x*(1 + 0.4175) = 1.4175*x
 
∴ x = 874.9/1.4175 = 617.2
Hi Jessica,
 
You must 1st substitute the value of y into the equation.
 
874.90 = (x*.4175) + x
 
874.90 = .4175x + x
 
874.90 = 1.4175x
 
Now divide each side of the equation by 1.4175.
 
874.90/1.4175 = 1.4175x/1.4175
 
874.90/1.4175 = x
 
x = 617.213404
Hi Jessica,
 
For this algebra equation, you'll want to use substitution. Take the value of y (874.90) and plug it into your equation.
 
874.90 = (x * 0.4175) + x
 
Now let's combine the terms on the right side of the equation.
 
874.90 = 1.4175x                            (because 1x + 0.4175x = 1.4175x)
 
Next, divide both sides by 1.4175
 
874.90/1.4175 = x       
 
So, x is approximately 617.21
 
(Note, it's always a good idea to check your answer. To do that, plug our answer for x back into our original equation and see if y turns out to be 874.90.)
D'oh!, of course zeroth, make sure you copy down the problem right :-)
 
 
First, Combine like terms:
 
y = (x * .4175) + x = 1.4175 * x
 
y = 1.4175 * x
 
Second, solve for x (get x by itself):
 
Multiply both sides by (1/1.4175)
 
(1/1.4175) * y = (1/1.4175) * 1.4175 * x
 
y / 1.4175 = (1) * x
 
x = y / 1.4175
 
Finally, substitute in your value for y:
 
x = 874.90/1.4175 = 617.2134ish
(or 8749000 / 14175 = 349960 / 567 if that's how you roll)
