Question

I need to know how to do these

Answer 1

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.

`√(1) = 1`

Therefore, X=1.
