2x-4
x = number
twice = 2 times x
less = -
and 4 = 4
put it all together and you get the answer (2x-4)
2X-6
5-w=
32 - n/2
4x - 5
3n-9
As an algebraic expression it is: 2x-9
2x-3
eight less than twice a number
As an algebraic expression this is written 2x - 12, where x is the unknown number.
The corresponding expression would be 2x - 6 = 4.
x / (2y - 7)
2x-3 , where x is the number referred to in the question
Let the unknown number be x and so the algebraic expression is: 2x -13
2X-6
2w - 10
4<x
a - 4
