Answer:
x = 5
Step-by-step explanation:
Simplify. First, combine like terms:
3x - x + 2 = 12
(3x - x) + 2 = 12
(2x) + 2 = 12
2x + 2 = 12
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

& is your order of operation.
First, subtract 2 from both sides:
2x + 2 (-2) = 12 (-2)
2x = 12 - 2
2x = 10
Next, divide 2 from both sides:
(2x)/2 = (10)/2
x = 10/2
x = 5
5 is your answer for x.
Check: Plug in 5 for x in the equation. Solve:
3(5) - (5) + 2 = 12
15 - 5 + 2 = 12
10 + 2 = 12
12 = 12 (True)

Answer:
Kendra ate 1/4 pounds of blueberries.
Step-by-step explanation:
The amount of blueberries Sean had = 1/3 pound
The amount of blueberries Kendra ate = 3/4 of Total available
= 3/4 of (1/3 pounds)
Now, we need to find out the 3/4 amount of 1/3 pound.
3/4 of 1/3 pound = 
⇒ 3/4 of the amount 1/3 pound = 1/4 pound
Hence Kendra ate 1/4 pounds of blueberries.
