Answer:

<h2>x= -3</h2>

Step-by-step explanation:

- 2x + 3 = 9 \\  - 2x = 9 - 3 \\  - 2x = 6 \\  \frac{ - 2x}{ - 2}  =  \frac{6}{ - 2}

x =  - 3

Answer: x = -3

Step-by-step explanation: To solve for x, we must first isolate the term containing <em>x</em> which in this problem is -2x.

Since 3 is being added to -2x, we subtract 3 from

both sides of the equation to isolate the -2x.

On the left, the +3 and -3 cancel out and on the right, 9 - 3 is 6.

So we have -2x = 6.

Now we can finish things off by just dividing

both sides of the equation by -2.

On the left the -2's cancel and on right, 6 divided by -2 is -3.

Thus, the solution to this equation is x = -3.
