1. Charlie's solution is incorrect because Charlie subtracted 5 instead of dividing 5. Charlie should do Step 1: 5x = 30
                                             
                                              Step 2: x = 30÷5

                                              Step 3: x = 6

2. This equation has 1 solution

Answer: A) Yes, his solution is incorrect.

B) The given equation has 1 solution.

Step-by-step explanation:

A) Here, the given expression is,

[tex]5 x = 30[/tex]

Thus, the steps of solving the given expression are as follow,

Step 1: [tex]5 x = 30[/tex]

Ste 2 : [tex]x=\frac{30}{5}[/tex]

Step 3 : [tex]x = 6[/tex]

Hence, by the above explanation,

It is clear that the given steps of the solution are incorrect.

B) Since, x has only one value which is 6,

Hence, the given expression has only one solution.
