3 less than twice n is 2n-3
The number is 7.
Let the unknown number be x and so the expression is: 2x-3
Let the number be x and so if 2x-3 = 13 then the value of x works out as 8
I'm not clear on what you're asking here, but if you want that written as an equation, it is: 2x - 3
2x-3
This means that X=2N-3.
2x-3
3 less than twice n is 2n-3
2x-3 , where x is the number referred to in the question
The number is 7.
the equation is 2x + 4 = x - 3 solving it yields x = -7
Let the unknown number be x and so the expression is: 2x-3
Suppose you start with x. Twice x is 2x. Three less than that is 2x-3 So 2x-3 = x Add 3 to both sides: 2x = x + 3 Subtract 1x from both sides: x = 3. You started with 3.
5+5=1010-7=3the answer is 3
2x-3=x+2 answer x=5
There are an infinite number of them. 2/3, 3/4, 3/5, 5/8, 7/8, 15/16.... Any fraction where the denominator (bottom number) is greater than the numerator (top number), AND the denominator is less than twice the numerator. So for example 2/3 above. Numerator = 2, denominator = 3 which is less than 2. Twice 2 is 4, and 3 < 4.
