Answer:
So..how was the test?
Step-by-step explanation:
Did you pass???
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
That's answer.
You didn't show us much of the page with the question on it,
so we can't be sure of exactly what you're working on in math.
If you're working with things like squares and rectangles, then
'L' and 'W' are often used to represent the Length and Width of
shapes drawn on paper, or even Length and Width of 3D objects
like blocks or boxes.

Answer:
x = 2.6667 (rounded)
Step-by-step explanation:
Move the constant to the right side and change its sign.
3x = 7 + 1.
Add the numbers.
3x = 8.
Divide both sides by 3.
x = 8/3 = 2.6667 (Rounded to the nearest ten-thousandth).
Hope this helps.
