SOLUTION: Can someone check this and see if I have done this correctly? thank you
Solve for x:
3(2 + x)= 5x - 4.2
6 + 3x = 5x - 4.2
- 3x = -3x
6 = 2x - 4.2

Solve for x:
3(2 + x)= 5x - 4.2
6 + 3x = 5x - 4.2
- 3x = -3x
6 = 2x - 4.2
+4.2 = + 4.2
10.2 = 2x
5.2 = x

Answer by BGluvsmath(64) (Show Source): You can put this solution on YOUR website!
3(2 + x)= 5x - 4.2
6 + 3x = 5x - 4.2
- 3x = -3x
6 = 2x - 4.2
+4.2 = + 4.2
10.2 = 2x
5.2 = x
You did everything right except for the last step. You didn't divide correctly. The answer should be 5.1.
FYI, a good check of your work is to go back to the original equation and put the solution in for the variable. If it works out, you know the answer is right.
