Answer:

x=-3

Step-by-step explanation:

Move the 9 to the other side of the equal Sign making it negative

Then also move the -30 to the other side to isolate the term 9x

-3 + 30 = 27

Divide both sides (which should now have -9x = 27) by -9x to isolate the variable

27/-9x = -3

Answer:

[tex]\Huge\boxed{\mathsf{\Rightarrow X=-3}}}[/tex]

Step-by-step explanation:

Isolate x on one side of the equation.

First, switch sides.

9x-3=-30

Next, add 3 from both sides.

9x-3+3=-30+3

Solve.

-30+3=-27

9x=-27

Then, divide by 9 from both sides.

9x/9=-27/9

Solve.

Divide the numbers from left to right.

-27/9=-3

X=-3

In conclusion, the final answer is x=-3.
