Part A: Write an algebraic expression for 6 more than 7 times a number.

The expression can be written as

= 6 + 7x

Hence if we are asked to solved for x, we simply need to transpose 6 to the other side of the equation, and then divide both sides by 7. We must take note that in transposing a number, the sign changes.

7x = -6
7x/7 = -6/7
x = -6/7

Final answer:

= 6 + 7x

Part B: Write a verbal expression for 3(n + 8).

The expression can be written as,

Three times the sum of a number and 8.

We've used the word sum to denote the operation of addition, and times to denote the operation of multiplication.

Final answer:

Three times the sum of a number and 8.
