Solve for x: 2(10-2x) = 4(3x + 1). Write your answer as a fraction.
qwelly [4]

Answer:

\boxed{x=1}

Step-by-step explanation:

2(10-2x) = 4(3x + 1)

\sf Expand \ brackets.

20 - 4x = 12x + 4

\sf Subtract \ 12x \ and \ 20 \ from \ both \ sides.

20 - 4x - 12x - 20 = 12x + 4 - 12x - 20

-16x = -16

\sf Divide \ both \ sides \ by \ -16.

\displaystyle \frac{-16x}{-16} =\frac{-16}{-16}

x=1

A= P(1+r)^t, where P= initial value, r= interest rate in %, and t = number of years.
However, if there isa decrease in value, the formula becomes:

A= P(1-r)^t and in our case :

A = 30,000(1- 0.24)^t  OR A = 30,000(0.76)^t
