36 - x
88
As an algebraic expression it is: 9-x
x-7
x-2
Lets assume the number = x. Also the expression means a function of x, f(x) which is often simply called y.So to show less than a number (x) the expression would read:f(x) = x-5 or y = x-5 Hope this helps.
2X-6
In algebra it is: 36-x
As an algebraic expression it is: 9-x
That expression is x-6.
let the no. be 'x' therefore, the expression of 5 less than a no. is, x-5
x-7
It is: x-5
The expression is: x -15
x - 8
x - 11
It is: x-5
x - 10
It is: x-5
