30 points if you can answer my question justify each step in solving the equation by writing a reason for each statement. given: 6x = 3 ( x + 4 ) prove: x = 4

Step-by-step explanation:

6x=3(x+4)

First of all multiply the R.H.S by 3

6x=3x+12

Now move all the terms containing x on the Left Hand Side

6x-3x=12

Now subtract 3x from 6x

3x=12

Now divide the both sides by 3

3x/3=12/3

x=4

Hence it is proved that x=4...

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
