lets presume the number is X:
2(x+x)+2
"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
To write twice the sum of a number and four, let the number be represented by the variable ( x ). The sum of the number and four can be expressed as ( x + 4 ). Therefore, twice this sum is written as ( 2(x + 4) ).
sum - means addition less - means subtraction twice - means multiply by 2
2 + 2x = 36
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
Fifty Two
18 is the only number that matches these criteria.
The units digit of a two digit number exceeds twice the tens digit by 1. Find the number if the sum of its digits is 10.
To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.

The difference between a number x and twice y is equal to fifteen.
