Answer
$6(x +3) = 33$.
Work Step by Step
First identify the task. In this case, it is to express "the product of six and a number increased by three is thirty-three" as an equation. We are told to assume the number is "x". A method to solving this problem is to divide the given statement into sub parts and then combine each of these parts into an equation.
"The product of six and a number" can be expressed as "$6x$".
"increased by three" can be expressed as "$+3$".
"Is equal to three" reminds us to connect the two sides with an equals sign, "$=33$".
By putting these together, the answer is $6(x +3) = 33$.
