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.

That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.

root

Possibly the solution to an equation

The equation is [ 5y = 35 ].The solution to the equation is [ y = 7 ].

No.

No.

No. That is because 2 - 8x is an algebraic expression, not an equation. And since it is not an equation, it does not have a 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
