Answer:

x = 19

Step-by-step explanation:

3(x - 9) = 30

Divide both sides by 3 to isolate the binomial.

x - 9 = 10

Add 9 to both sides to isolate x.

x = 19

Check your answer by plugging x = 19 back into the equation.

3(x - 9) = 30

3(19 - 9) = 30

Subtract.

3(10) = 30

Multiply.

30 = 30

Your answer is correct.

Hope this helps!

Answer:

x = 19

Step-by-step explanation:

First, we must distribute 3(x-9) = 30

[tex]3x - 27 = 30[/tex]

Now, that we've distributed this equation, we can proceed.

Secondly, since there is a subtraction sign in front of 27, we must do the opposite, addition.

Add 27 to 27 and 30:

[tex]3x - 27 = 30[/tex]

[tex]-27 + 27 = 0[/tex]

[tex]30 + 27 = 57[/tex]

Furthermore, -27 + 27 is 0, so it cancels itself out. Also, since we added 30 and 27 and got 57, replace 30 with 57.

[tex]3x = 57[/tex]

Lastly, divide 57 by the number in front of coefficient, 3.

[tex]57/3=19[/tex]

Therefore, [tex]x=19.[/tex]
