    Tanner is 15 and lexi is 18. if you set up an equation you can figure this out. lexi’s age is x and tanner’s age is x - 3 because he is three years younger than lexi. add the two together: x+x-3. we know that this is equal to 33 as stated in the problem. then the equation is x + x - 3 = 33. add three to each side to simplify. x + x = 36. x + x are likes terms so you can combine them to 2x. this is still equal to 36. therefore, 2x = 36. divide each side by two to get x on its own to figure out lexis age, which is 18. if tanner is three years younger, he must be 15
