2*4 + 3*x = 34

Half of 18 is 9 and 5+4 = 9 so the number is 5

twice a number can be 2x and six less than it is 2x-6.

Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)

Your equation would be 5(x + 4). In this case it's easiest to work backwards, starting with the "sum of a number and four" part of the problem. This is simply written as x + 4, since we don't know what "a number" is referring to and have to call it x. Then we just need to multiply that answer by 5, so we'd write the equation as 5 * (x + 4) or 5(x + 4). Make sure you have the parentheses, because if not it changes the answer entirely.

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.

Let the number be x:- If: 4+2x = 12 Then: x = 4

If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.

2*4 + 3*x = 34

Let's go through the process: Add 1 to 456: 456 1 = 457 456+1=457 (does not contain the digit 4) Add 2 to 456: 456 2 = 458 456+2=458 (does not contain the digit 4) Add 3 to 456: 456 3 = 459 456+3=459 (does not contain the digit 4) Add 4 to 456: 456 4 = 460 456+4=460 (contains the digit 4) Here, adding 4 gives us 460, which includes the digit 4. Therefore, the smallest number you can add to 456 to get a sum that uses the digit 4 is 4 4 Read More...tinyurl .com/sx3dkfpw
