The equation for the statement "A number n is 5 more than 12" can be written as n = 12 + 5. This equation represents that the value of n is equal to 12 (the initial number) plus 5 (the additional amount). Therefore, n = 17 is the solution to the equation.
y = 3x + 5
The solution set is the answers that make an equation true. So I would call it the solution.
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}).
The number that can replace a variable in an equation to make it a true equation is called the solution or root of the equation. This number satisfies the equation when substituted for the variable. In algebra, finding the solution involves solving for the variable by performing various operations to isolate it on one side of the equation. The solution is the value that balances both sides of the equation, making it true.
