To solve the expression, we must know about an expression.
<h2>Expression</h2>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
The solution of the expression is 2a.
<h3>Given to us</h3>
<h2>Solution</h2>
Multiplying both we get,
Taking 4 as common from the numerator,
Canceling (a+1) from both numerator and denominator,
Expanding further,
Canceling 2 and a,
= 2a
Hence, the solution of the expression is 2a.

Answer:
$7,000
Step-by-step explanation:
Let x = the part of $16,000 that was lent at 8%.
Then 16,000 - x is the part that was lent at 16%.
The interest earned at 8% is 0.08x.
The interest earned at 16% is 0.16(16,000 - x).
The total interest earned is 0.08x + 0.16(16,000 - x).
The total interest earned was $2,000, so
0.08x + 0.16(16,000 - x) = 2000
Now we solve for x to find out the amount lent at 8%.
0.08x + 0.16(16,000 - x) = 2000
0.08x + 2560 - 0.16x = 2000
-0.08x + 2560 = 2000
-0.08x = -560
x = 7000
