let x = first number
let y = second number
x + y =20
(x + y)/3
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------
(x + y)/20= n
xy-3 where x and y are the two numbers.
An algebraic expression need not be a difference of two terms.
(x + y)/3
(x + y)/20
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------
(x + y)/20= n
a common factor
3x+2
x+y=180, solve for yy=180-x
xy-3 where x and y are the two numbers.
An algebraic expression need not be a difference of two terms.
They are two terms of an algebraic expression.
It is two terms of an algebraic expression in the form of: x-15y
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
