Answer:
A - Here is your answer that you asked without clues
X = 4. First you divide by 6 on both sides to get rid of the parentheses, then add 8 to both sides and get x alone on the left.
3ˣ (x² - 3)
Basically, just multiply everything together.
Step 1 : 3x × x² = 3x³ because when multiplying exponents, all you're really doing is adding them on top. So, x + 2x = 3x! But, they are exponents, so you get 3x³.
Step 2 : 3x ˣ × (-3) = -9ˣ
Now, our new question is : 3x³ - 9x
You wouldn't simplify this because x³ is NOT the same as x.

U = 2x - 2
We simply need to isolate x :) That just means that we need to get x onto it's own side of the equal sign.
So, add 2 to both sides.
2 + u = 2x
Then, divide both sides by 2.
2 + u ÷ 2 = 2x ÷ 2
Simplify.
1 + u/2 = x
So, x = 1/2u + 1
