Answer:
<em>See below</em>
Step-by-step explanation:
In this example we are to consider the equation 2x - 5 = 4x + 12, and are asked to solve for x. Well let us take the first approach, a mathematical one;

Now consider the explanation, " talking over a phone to a friend. "
First you would subtract 2x on either side of the equation, canceling the 2x on one side, and subtracting 2x from 4x on the other, resulting in the simplified equation - 5 = 2x + 12. Subtracting 12 from either side we cancel the 12 on one side, and subtract - 12 and - 5 on the other. We now get - 17 = 2x. Dividing 2 on either side, x = - 8.5!
Answer:
the answer is Any Real Number
because 4(x + 1) = 4x + 4 for all value of x

Answer:
Present value of contributions is $24,106.15
Step-by-step explanation:
Weekly rate=9%/52weeks= 0.173%
Weekly contributions $50
Number of weeks=20years×52weeks=1040
Present value of contribution=$50(1-[(1+9%/52)^-1040 /(9%/52)
Present value of contribution= $24,106.15
