7n+5
5+4x
This expression would be 3x-7.
Let the number be x and so the algebraic expression is: 6x+2
7(n+3)
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
7x + 2
Let x be the number and so: 25 = 4x+7 and the value of x is 4.5
x+9x
The expression is: 30+3x2
5+4x
7/ 3/
9X + 7
Let the number be x and so the expression is: 2+6x
x3 + 4x
This expression would be 3x-7.
y = 4x + 6
The algebraic expression for 7 decreased by 4 times a number can be written as ( 7 - 4x ), where ( x ) represents the number. This expression captures the operation of subtracting four times the variable from seven.
