Which is the best reason why step 1 is a good first step in the solution shown?` WILL GIVE BRIANELIST

Multiplying by 5 isolates the x on one side of the equation

Step-by-step explanation:

This is so you can solve for the variable x.  By isolating you get the get the variable on its own so you know what the varible itself is equal to, which in this case is 75.

Multiplying by 5 isolates x on one side of the equation

Step-by-step explanation:

When you solve equations like that, your goal is to get the variable by itself

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
