One subtracted from the result of tripling x and is equal to two times the difference of x and 4. Find x
Evgen [1.6K]

Answer:

5

Step-by-step explanation:

If two is subtracted from a number: let's give the number a name and call it  X . And this difference is tripled: so we get  3(X−2) . The result is 4 more than the number, so

3(X−2)=4+X .

We want to know  X  so we need to get it to one side of the equation. That's done by repeatedly doing the same operation on both sides of the equation. First get rid of the parentheses:

3X−6=4+X.  

Now subtract  X  and add  6 :

2X=10  

Divide by 2:

X=5
