By using the Distributive Property, you would multiply 3 into the parenthesis (3 · x and 3 · -4)
3(x - 4) = 24
3x - 12 = 24
Then, you would solve like any normal one-step equation.
3x - 12 = 24
+12 +12
__________
3x 36
__ = __
3 3
x = 12, which is your final solution.

3.2 . I don't really know how to explain this, but I need to write at least 20 characters to give you my answer.
Answer: The answer is actually 8 4/7
Step-by-step explanation:
Because...
7/6y-8=2
Add the 8 to the other side
7/6y=10
You then have you divide 7/6y by 7/6, then do it to the other side giving you 60/7.
That gives you a mixed number of 8 4/7.
Answer:
0.915
Step-by-step explanation:
move the decimal two to the left and take a the percentage
Second binomial formula
(a - b)^2 = a^2 - 2ab + b^2
(3x - 4)^2 = (3x)^2 - 2 × 3x × (-4) + (-4)^2
=9x^2 + 24x - 16
