Answer:

Explanation:

4x – 5 + 2x = –11

4x + 2x = –11 + 5

6x = -6

x = -1

Check:

4x – 5 + 2x = –11

4(-1) - 5 + 2(-1) = -11

-4 - 5 - 2 = -11

-11=-11

Answer:

Explanation:

First you should simplify the terms, because on the left side there are multiple x's. (Tip! When terms are on the same side of the equal sign you can always simplify it!) Something like this:

6x-5=-11 (Since the 4x is positive and so is the 2x you just add them together)

Second, to get rid of the -5 add 5 to each side of the equal so the -5 in the original question becomes 0.

6x-5+5=-11+5 (The underlined becomes 0)

Third simplify that equation

6x=-6

Forth, divide both sides by the same factor, in this example using 6 would be the easiest.

6x/6=-6/6

Fifth, one again simplify.

x=-1

Now to verify to make sure it's correct. Add -1 where all the x's are. like this:

4(-1)-5+2(-1)=-11

The answer to x is -1!
