5+5=1010-7=3the answer is 3
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
If the number is N then 2N - 5 = 7 then 2N = 12 so that N = 6
To find 2 less than twice a number, you would first multiply the number by 2 and then subtract 2 from the result. In mathematical terms, this can be represented as 2x - 2, where x is the number in question. For example, if the number is 5, then 2 less than twice the number would be 2(5) - 2 = 10 - 2 = 8.
Six times a number minus five is less than twice the number plus ten. 6 * n - 5 < 2 * n + 10 6n - 5 < 2n + 10 4n - 5 < 10 4n < 15 n < 15/4 This statement will hold true for all n < 15/4
