You haven't included "the following" part of your question! However, your answer will look (or describe something) similar to this:
2x + 6 = 22
2x = 22 - 6
2x = 16
x = 8
If the alternatives you are looking at are descriptions rather than algebra then your answer will look similar to:
* Subtract 6 from both sides of the equation / move the "plus 6" to the other side of the equation and change it to "minus 6".
* Divide both sides of the equation by 2.
It really depends on the type of equation, but in the simpler cases - those that you are likely to encounter in high school algebra - you will usually need to replace the purported solution into the original equation, then simplify the equation as appropriate. If this results in a true statement (for example, "5 = 5"), then the solution is correct; if you get a false statement (for example, "1 = 0"), then the purported solution is not correct.
Definitely.The equation [ x^2 = 4 ] has two solutions.x = +2x = -2The square root of any number can be a positive number or its negative. The solution for a quadratic equation often has two different values. However having two different values is still a single solution.
no it can't be
7-2 IS positive. You do not need an equation for it. And if it were not positive, no correct equation would show it to be positive.
The equation above is correct.
You should substitute your solution in the equation. If the solution is correct you will receive equality. Otherwise your solution is wrong.

There is no graph because there is no equation - only an expression.
That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.
to find a linear equation the roots must have been given in the question. to check whether its correct or not use this method. x2-(SOR)x+POR=0. SOR = sum of roots, POR = product of roots. if your SOR and POR is similar to your final answer, then the solution is correct

You would have a reasonable shot at finding the correct solution.
Multiplying the first equation by -3 gives -21x - 6y = -48 but the other equation gives 24 as the value of the same expression, so you are correct, there is no solution
The correct sentence is: "This describes who she was." In this case, "who" is the subject complement of the verb "describes," so the nominative form "who" is appropriate.
When he arrives he will call you.
Plug your answer back into the original equation.Example:3x+15=21x=23(2)+15=21
While you were working she arrived. When I was working on x project she arrived. She arrives on time daily.
