Let the number be x:-
If: 4+2x = 12
Then: x = 4
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) ).
It is 2*(x+4)
4
.5[12+(t/4)]
The number is less than 4.
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
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) ).

4
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.
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6

4/(n + 12)
12-8 = 4 and 2*4 = 8
.5[12+(t/4)]
2*4 + 3*x = 34
3x + (-4) ≥ 2x + 8
