How about x+4 = 0 ?
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
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}).
-4 and 4
Without an equality sign the given terms can't considered to be an equation and so therefore it has no solution.
9 - 4 = 5
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
x = 0
2x 4 10 is not an equation.
a solution to an equation is the answer
10 (-2) 5 (-4)
[ x = 11 ] is.
