Question

Solve for x:

x - 0.2x + 0.07(x - 0.2x) = 73.53

Answer 1

Distributive property and adding like terms ought to clean this up.

Answer 2

x-.2x+.07x-.014x=73.53
1.486x=73.53
50.8=x

Answer 3

Soo..

-0.2x + 0.07x + 0.014x = 73.53

then...
-0.116?

Answer 4

@pkjha3105 Your answer must be wrong because it isn't even listed.

Answer 5

Is \[x \approx85.90\] listed? If so, I will explain how I got it.

Answer 6

Yes, it is listed

Answer 7

You actually don't have to use distributive at all;
\[x-0.2x+0.07(x-0.2x)=73.53\]
In this equation, it helps to write all of the x's that are alone as 1x's. So,
\[1x-0.2x+0.07(1x-0.2x)=73.53\]
Now solve what's in parentheses first,
\[1x-0.2x=0.8x\]So,
\[0.8x+0.07(0.8x)=73.53\]
Now, \[0.07 \times0.2x=0.056x\]So,\[0.8x+0.056x=73.53\]
\[0.856x=73.53\]Divide both sides by 0.856 to get x alone;
\[\frac{ 0.856x }{ 0.856 }=\frac{ 73.53 }{ 0.856 }\]
\[x = 85.89\]
or
\[x \approx85.90\]
got to love decimals, haha.
