Given:


7x+3x-18=6(x+3)

The solution will be done by performing the justifications provided as follows:

1) Given


7x+3x-18=6(x+3)

2)Distributive property or Multiplicative property of equality:


(7+3)x-18=6x+18

3)Addition property of equality:


10x-18=6x+18

4)Combine like terms:


10x-6x=18+18

5)Distributive property and addition property of equality:


(10-6)x=36

6)Subtraction property of equality:


4x=36

7)Division property of equality:


\begin{gathered} x=(36)/(4) \\ x=9 \end{gathered}

These are the steps followed and result is x = 9.
