Question:

If 12 less than 4 times a number is 8, the number is 5. Write a different sentence where the unknown number is also 5.

Addition and Subtraction

We should just form an equation with 5 contained in it.

We can calculate the value of a*5 + b = x, and write the statement as :

If 'b' more than 'a' times a number is x, then the number is 5.

Answer and Explanation:

If 10 more than 8 times a number is 50, the number is 5.

Because, {eq}10+8x = 50 \implies 8x = 40 \implies x = \frac{40}{8} = 5 {/eq}.
