Let Mia's score be 
. Then, Erick scored 10 more than Mia, so his score is 
. Isabelle scored 16 less than twice Mia's score, so her score is 
. We can see that 
is the sum of these variables, so the expression represents the total of their scores in this scenario. Moreover, we recall that the variable in the expression, , represents Mia's score.
To simplify this expression, we add up the variables and the numbers separately, giving us
. Therefore, in simplified form, the expression is equal to 4x - 6. The constant term in an expression is the term not multiplied by a variable, so in this case, it is -6.
