Answer:

2x-12

Step-by-step explanation:

First you distribute the -2 to the x and +3

this will make you expression be:

4x-6-2x-6

you then do -6+-6

this will make your expression be:

4x-12-2x

After you get this you have to combine like terms. the like terms in the expression are the two with x being you variable. 4x and -2x.

Once you have combined like terms your solution should be:

2x-12

A 20-gallon salt-water solution contains 15% pure salt. How much pure water should be added to it to produce a 10% solution?
Elanso [62]

15% of 20 gal = 0.15 * 20 gal = 3 gal, so the solution contains 3 gal of salt.

If we add <em>x</em> gal of water to the solution, we end up with (20 + <em>x</em>) gal of solution. We want the new mixture to have a concentration of 10%, or

10% of (20 + <em>x</em>) gal = 0.1 * (20 + <em>x</em>) gal = 2 + 0.1<em>x</em> gal

of salt.

The amount of salt in the tank hasn't changed. Solve for <em>x </em>:

2 + 0.1<em>x</em> = 3

0.1<em>x</em> = 1

<em>x</em> = 10 gal

Since all of these numbers have the same variable they can all be added up to get a sum of 10a which is its simplified form.
