6 - x = 2(x - 6)
the first step, following PEMDAS, is to distribute the 2 to the inside of your parentheses:
6 - x = 2x - 12 ... subtract 2x
6 - 3x = -12 ... subtract 6
-3x = -18 ... divide by -3
x = 6 is the answer
Answer:

Step-by-step explanation:
First, multiply the 3 and the 7 together, and then "multiply" the exponents -8 and 3. (However, when "multiplying exponents, you're really just adding them together: -8 + 5)

Answer:
A ) The Amount which will be saved after five years is $ 5742.4
B ) The compound Interest is $ 1742.4
Step-by-step explanation:
The Principal deposited at the end of each year = $ 4000
The rate of interest = 7.5 % compounded annually
The time period = 5 years
From compounded method :
Amount = principal × 
or, Amount = $ 4000 × 
Or, Amount = $ 4000 × 
or, Amount = $ 4000 × 1.4356
∴ Amount = $ 5742.4
A ) The Amount which will be saved after five years is $ 5742.4
B ) The compound Interest = Amount - principal
Or, C I = $ 5742.4 - $ 4000 is $ 1742.4 Answer
