There are an infinite number of equations with this solution, eg x = 6 - 10; x = 45678 - 45682; x squared = 16 etc etc

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.


An equation that has no solution is called an equation that has no solution.


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


a solution to an equation is the answer


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}).


Without an equality sign the given terms can't considered to be an equation and so therefore it has no solution.


A solution is the answer to an equation.


2x 4 10 is not an equation.


An algebraic equation has (at least one) variable, usually called x. To solve the equation means to figure out the value of x. For example, in the equation x + 4 = 7 the solution is x = 3, because 3 + 4 = 7.


(2, 3) is a solution only if it satisfies the equation. x + 5y = 4 (2) + 5(3) =? 4 2 + 15 =? 4 17 = 4 False Therefore, (2, 3) is not a solution to the given equation.


In algebraic terms, the solution is the answer to equation.



If for example: 4y = 16 Then: y = 4


There can be no solution since there is no equation (nor inequality) in the question.

If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)


how many solutions does the equation have? 4x+1=5+2(2-4) a. one solution b. infinite solutions c. no solution


Yes it is. The solution is: y=4 .


A solution to an equation is a set of values for the variables in the equation which make it true.


Given the equation 3x + 4 = 7, will there ever be more than one solution for x?



X4.3 is not likely to be the solution of a normal equation.


y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
