look at step by step solution shown below and fill in the missing stepthe solution is finding the missing step

Let's complete the solution of the following expression:
[tex]\text{ 65= 3(2x + 5) + x + 15}[/tex]We get,
[tex]\text{ 65= 3(2x + 5) + x + 15}[/tex][tex]\text{ 65= 6x + 15 + x + 15}[/tex]The next step should be,
[tex]\text{ 65= 7x + 3}0[/tex]The missing step is adding all like terms which will be 65 = 7x + 30
