x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
x - 9 is an expression, neither an equation not an inequality. An expression cannot have a solution.

-12 = x+9 x+9 -9 = -12 -9 x = -21
Expression.
The GCF of 9 and 21 is 3.
x - 9 is an expression, neither an equation not an inequality. An expression cannot have a solution.
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
9/x
X+9
The expression is 9*x.
It is a binomial expression.
It is a binomial expression.
The algebraic expression for the sum of x and 9 is x + 9. In this expression, x represents a variable that can take on any value, and 9 is a constant. When you add x and 9 together, you are combining the variable x with the constant 9 to get the sum. This expression can be simplified further if needed, but the basic form is x + 9.
