30 is the coefficient because it is attached to the variable, x, a substitution for an unknown number. 65 is being added to whatever 30x
is. 170 is the sum of the equation.

Hi!

[tex]30x+65=170[/tex]

[tex]30x+65-65=170-65[/tex]

[tex]30x=105[/tex]

[tex]\frac{30x}{30}=\frac{105}{30}[/tex]

[tex]x=\frac{7}{2}[/tex]

Explanation: First you had to subtract by 65 from both sides. It gave us 30x+65-65=170-65. Then simplify, you can also divide by 30 from both sides. And simplify, and it gave us the answer is x=7/2 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day.-Charlie
