Answer:
Isolating a variable means rearranging an algebraic equation so that a different variable is on its own. The goal is to choose a sequence of operations that will leave the variable of interest on one side and put all other terms on the other side of the equal sign.
Step-by-step explanation:
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.
Add 5 to both sides to get x alone and you will have your answer which is x= -3

Answer:
Do by Transposition..
Step-by-step explanation:
0.5x=287-78.2
0.5x=208.8
X=208.8-0.5
X=208.3
