Answer

The equation that meets the specifications of the statement is: $3x − 10 = 23$ Solving the equation, we get: $x = 10$

Work Step by Step

The product of $3$ and a number can be translated to: $3x$ We subtract $10$ from this to get: $3x - 10$ The word "is" means "equals," so "is 23" translates to: $ = 23$ We combine both sides of the equation to get: $3x − 10 = 23$ The first step to solving this equation is to add $10$ to both sides to get: $3x = 23 + 10$ $3x = 33$ We then divide each side by $3$ to get $x$ by itself: $x = 10$
