one way is to let x^2=m, then you have an equation m^2+3m-28=0, and then you solve this quadratic equation for m, and you get: m=4, or m=-7... since m represents x^2, m can only be positive (if we are dealing with real numbers), so m=-7 is not possible solution... now if m=4, the x^2=4, and solving this equation: x=2 or x=-2
An equation is a true statement. [ 75 + 4 = -2 ] is a false statement.
The solution of an equation means the number that the variable must bein order to make the equation a true statement. If the variable has anyother value, then the equation is not true.For example, here's an equation:x - 4 = 2Can 'x' be 5 ? If it is, then 5-4=2. That's not true, so 'x' can't be 5.Can 'x' be 9 ? If it is, then 9-4=2. That's not true, so 'x' can't be 9.Can 'x' be 6 ? If it is, then 6-4=2. That's true. So '6' is the solution to the equation.

Well, it is hard to answer your question . . . "(-6x1y)m-4" is not an equation, you see. To be an equation, the formula needs to have an equals sign. Example: 6x+27 -17 = 32 is an equation and can be solved. However, your stated formula can be better written like this: m-4 (-6y)
The equation is N = 4*M.

For a value to be a solution to an equation, when you substitute the value for the variable, the equation becomes true. 4+B=6 B is the variable. 2 is the solution Substitute 2 for B 4+2=6 The equation is true.

A number that makes an equation true is a solution. If there is more than one answer to an equation (such as an equation like): (x-2)(x+4)=0 then it is called a solution set (and in this case would be x={-4, 2}).
