Question

What does it mean for a number to be the "solution" to an equation?


Give an example of a variable equation and its solution.
Explain in complete sentences how you know that number is the solution.

Answer 1

a solution to an equation means the number (or numbers) that will make the equation true.

for example, the equation x+2=5.
x=9 is not a solution because (9)+2=5 is NOT a true statement.
but
x=3 is a solution because (3)+2=5 is a true statement.
