Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
2x-3=x+2 answer x=5
x4 - 3
Let the number be x and so the expression is: 4x -7
write the number that is 100 less
There are quite a few details to get used to. For instance, "x minus 3" would be x - 3. "n subtracted from 7" would be 7 - n. "5 less than y" would be y - 5. "6 decreased by z" would be 6 - z.
47< t
h-7
Expressed algebraically, this is equal to 4x - 500.
2x-3=x+2 answer x=5
( n - 16 )
As an algebraic expression it is: 2x-9
x-2
3n-30
x + (13-10)
x^2 - 7
x4 - 3
Let the number be x and so the expression is: 4x -7
