Hey!

Let's write the problem.
2x-4-5x=2
Add like terms...
-3x-4=2
Add 4 to both sides.
-3x-4+4=2+4
-3x=6
Divide both sides by -3.
\frac{-3x}{-3}=\frac{6}{-3}

Our final answer would be,
x=-2

Thanks!

A car seller buys a car from a manufacturer for $10,000. He increases the cost by 5 percent. What is the markup amount?
torisob [31]
We know that:

The markup is the price added to the cost price of goods...

To find the markup, we must multiply the percent increase by the original price (before markup).

So:

10,000 x 5% (or 0.05) = ?

10,000 (You do not have to follow my way of multiplying, do what is comfortable for u)
x       5 (Ignore the decimals then we move it after we get the answer) 
----------
50,000 move the decimal back 2 places so it is 500

The final answer is:

The markup amount is $500...

What is the value of k in the equation StartFraction k Over 3 EndFraction minus 5 = 34?
12345 [234]

\huge\text{$k=\boxed{117}$}

\displaystyle\frac{k}{3}-5=34

To find the value of k, we need to isolate it on one side of the equation. Add 5 to both sides of the equation, then multiply both sides of the equation by 3.

\displaystyle\begin{aligned}\frac{k}{3}-5+5&=34+5\\\frac{k}{3}&=39\\\frac{k}{3}*3&=39*3\\k&=\boxed{117}\end{aligned}
