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/
Let the number be x and so the expression is: 2+6x
x3 + 4x
y = 4x + 6
9X + 7
This expression would be 3x-7.
Let the number be x and so the algebraic expression is: 6x+2
