==========================================================
Explanations:
- "Four times a number" gives us "4x". We then subtract off 6.
- The expression 2x represents "2 times a number", aka "the product of 2 and a number". We then divide that expression over 5 to get the quotient.
- Take any number x, and subtract off 7. For instance, if x = 10, then x-7 = 10-7 = 3, which shows that 3 is 7 less than 10.
- The term "quotient" means "result of division". So we divide 4 over 'e'
- The expression 9+x is the sum of 9 and some unknown number. The 6 out front means we multiply 6 with (9+x).
- The term "difference" means we'll be subtracting the terms.
- "ten times a number" translates to 10x, in which we increase that by 12 to get 10x+12
- The portion 20/x is the quotient of 20 over x. This is similar to problem 4. Then we increase the (20/x) by 7 to get (20/x) + 7
- The x-16 part is the difference of x and 16. That result is then divided in half.
