Answer:

x = -4

Step-by-step explanation:

-4 = 6x + 20

-24 = 6x

-4 = x

So, the answer is x = -4

I need to know how to do these
Allisa [31]

I'll do one, you can use it as a basis for your answer.

7x ^{2}    + 6 = 13

Subtract 6 from both sides to get X by itself.

7x ^{2}  = 7

Now we divide by 7 for both sides as well.

x {}^{2}  = 1

Now we find the square root of 1 to figure out X.

\sqrt{1}  = 1

Therefore, X=1.

my first answer in about a month. hope this helped.
