Watch this closely:
[ X+4 ].
h 14
If you call your number x, the expression would be 5x.
The algebraic expression would be 8n + 3, where n represents the unknown number.
Let the number be x and so the expression would be: x+20
To write the algebraic expression for "2 less than a number," first define the number as a variable, commonly ( x ). The phrase "2 less than" indicates subtraction, so the expression would be ( x - 2 ). Therefore, the algebraic expression is ( x - 2 ).

This expression would be 3x-7.
25x= 5
Y 12y
x+7=y
The corresponding expression would be 2x - 6 = 4.
Twice a number can be represented as 2x, where x is the unknown number. Adding 27 to this expression gives 2x + 27. Therefore, "twice a number plus 27" can be written as the algebraic expression 2x + 27.
Algebraic expressions are mathematical phrases that contain numbers, operations and at least one variable. An example of an algebraic expression would be : 4x + 3= 9x.
