The expression for "three less than x" is ( x - 3 ), and the expression for "five more than twice x" is ( 2x + 5 ). The product of these two expressions can be represented as ( (x - 3)(2x + 5) ). Thus, the expression representing the product is ( (x - 3)(2x + 5) ).
x = 5 + 2x - 3 x = -2
y = 3 + (-x) or y = 3 - x
2x-3=x+2 answer x=5

The expression for "three less than x" is ( x - 3 ), and the expression for "five more than twice x" is ( 2x + 5 ). The product of these two expressions can be represented as ( (x - 3)(2x + 5) ). Thus, the expression representing the product is ( (x - 3)(2x + 5) ).
2x - 3 = x + 5 x = 8
x = 5 + 2x - 3 x = -2
y = 3 + (-x) or y = 3 - x
2x-3=x+2 answer x=5
2x+3 where x is the unknown number
6x+3 where x=the number
The expression is: 3x+4
2 divided by 3 + x.
5=3+x
The algebraic expression for "3 more than a number" can be written as x + 3, where x represents the unknown number. In this expression, the variable x is being increased by 3. This expression can be simplified further if needed, but the basic form is x + 3.
