+2440 Do you mean \(2-x-2=4\)?
If so, I will solve it as so:
| \(2-x-2=4\) | Combine the like terms on the left hand side of the equation |
| \(-x=4\) | Divide by -1 on both sides to get rid of the negative on the x. |
| \(x=-4\) | |
If you are ever unsure if you have the correct value for your unknown, just plug it back into the equation:
| \(2-(-4)-2=4\) | Check to see if this is true; if it is wrong, you either made a mistake or you have an extraneous solution. |
| \(2+4-2=4\) | Subtracting a negative number is the equivalent of adding a positive one. |
| \(6-2=4\) | |
| \(4=4\) | 4=4 is a true statement and concludes that the value for x is correct. |
