how do i know whether to subtract or divide when isolating a number? (example, 2a, do i subtract or divide?)

Respuesta :

Answer:

Example 2a should be divided

When the variable is attached like 2a you divide to isolate. When it is 2+a you subtract 2 to the other side and when it’s -2+a you add to the other side!
