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.
