I am having trouble with these 2 questions.

1. 3x+7=-15

2. -2x-6=+12

What is x?

X is unknown until the Eqs has been solved. N or any letter can be used for the unknown.

1. 3x + 7 = -15.
Isolate 3x by subtracting 7 from both sides:
3x+7-7 = -15-7,
3x = -22,
divide both sides by 3:
X = -22/3 = -7 1/3.

2. -2x - 6 = 12.
-2x-6 + 6 = 12 + 6,
-2x = 18, X = 18/-2 = -9.

Sure! I can help you solve these two equations step by step.

1. 3x + 7 = -15:
To solve this equation, we need to isolate the variable x. We'll start by getting rid of the 7 on the left side of the equation. To do this, we'll subtract 7 from both sides:
3x + 7 - 7 = -15 - 7
This simplifies to:
3x = -22

Now, to isolate x, we'll divide both sides of the equation by 3:
(3x)/3 = -22/3
This gives us:
x = -22/3

So the solution to the equation is x = -22/3.

2. -2x - 6 = 12:
Similarly, we want to isolate x in this equation. To begin, we'll add 6 to both sides of the equation:
-2x - 6 + 6 = 12 + 6
This simplifies to:
-2x = 18

To isolate x, we'll divide both sides by -2:
(-2x)/-2 = 18/-2
This gives us:
x = -9

Therefore, the solution to the equation is x = -9.

I hope this helps! Let me know if you have any further questions.
