Question

Translate the sentence into an equation.Seven more than the product of a number and 3 is equal to 9.Use the variable x for the unknown number.

Answer 1

Let x represent a number.

Then, "the product of a number and 3" can be written in algebraic language as:

$3x$

The phrase "seven more than the product of a number and 3" is equivalent to "seven more than 3x", which can be written as:

$7+3x$

If that expression is equal to nine, then the whole sentence translates to:

$7+3x=9$
