In your own words, describe what it means for a number to be a solution to an equation. How do you check to see if a number is a solution to an equation?
for a number to be a solution to an equation, it has to satisfy the equation...it has to make the equation true.
for example : 2n + 6 = 10.....n is our unknown number 2n = 10 - 6 2n = 4 n = 4/2 n = 2...so the number that makes the equation true is 2
and to check if the number is a solution, we then sub that number back into the original equation to see if it makes the equation true. 2n + 6 = 10 2(2) + 6 = 10 4 + 6 = 10 10 = 10 (correct)
so our number (n) represents the number 2, and it does make the equation true
