Answer 2

It seems like you have a list of mathematical equations involving the variable "x." Let's solve each equation step-by-step:

1. 3 + x = 9

To solve for "x," you need to isolate it on one side of the equation. Here's how you do it:

Subtract 3 from both sides: 3 + x - 3 = 9 - 3 x = 6

So, the value of "x" in this equation is 6.

2. 10 - x = 7

Again, to solve for "x," isolate it on one side of the equation:

Subtract 10 from both sides: 10 - x - 10 = 7 - 10 -x = -3

Now, to get the value of "x," you need to multiply both sides by -1 to eliminate the negative sign: x = 3

So, the value of "x" in this equation is 3.

3. x - 4 = 5

To solve for "x," isolate it on one side of the equation:

Add 4 to both sides: x - 4 + 4 = 5 + 4 x = 9

So, the value of "x" in this equation is 9.

4. 4 = x = 6

This equation appears to be incorrect because there is more than one equal sign. An equation should have only one equal sign. If you meant to write it as:

4 = x + 6

Then, to solve for "x," isolate it on one side of the equation:

Subtract 6 from both sides: 4 - 6 = x + 6 - 6 -2 = x

So, the value of "x" in this equation is -2.

Please double-check the fourth equation to ensure its accuracy. If you meant something different, feel free to clarify, and I'll be happy to help!
