Question

Nine more than the product of a number and 3 is equal to 4

Answer 1

Equations

First, let's assume the unknown number to be f.

Then, the product of f and 3 is 3f;

9 more than that is 9 + 3f;

this equals 4, so, our equation is:

9 + 3f = 4

To solve for f, subtract 9 from both sides:

3f = 4 - 9

3f = -5

Divide both sides by 3:

f = -5/3

Therefore, the number is -5/3.
