x + 4 = 2x subtract x to both sides;
4 = x, so
4 + 4 = 2(4)
4 + 4 = 8 true

What is twice the sum of a number and 4?
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
What is Twice the sum of 4 and three times some number is 34?
2*4 + 3*x = 34
Find the smallest of four consecutive even integers if twice the sum of the second and third integers is equal to the sum of the first and fourth integers increased by fourteen?
Since we know that the integers are even and consecutive, we can call them x, x+2, x+4, and x+6, with x being the smallest of the four. twice the sum of the second and third can be written as 2(x+2+x+4)=4x+12 the sum of the first and fourth increased by 14 is x+x+6+14=2x+20 Then we can solve 4x+12=2x+20-->2x=8-->x=4 4
What is twice the sum of two numbers?
to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26
What is twice the sum of a number and 4?
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
What is twice the sum of x and 4?
x+4.
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
What twice the sum of a number x and 4 in expression or equation?
It is 2*(x+4)
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
Twice the sum of 4 and x is less than -16?
20
What is twice the sum of 4 and x is less than -16?
20
What is the sum of 4 and twice a number is 12?
Let the number be x:- If: 4+2x = 12 Then: x = 4
Twice the sum of four and x is three less than x?
Thus: 2*(4+x) = x-3, or x = -11.
What is Twice the sum of 4 and three times some number is 34?
2*4 + 3*x = 34
Twice divided by the cube of the sum of x and 2?
Twice divided by the cube of the sum of x and 2 is equal to 2 times the reciprocal of ((x + 2) cubed)).
Find the smallest of four consecutive even integers if twice the sum of the second and third integers is equal to the sum of the first and fourth integers increased by fourteen?
Since we know that the integers are even and consecutive, we can call them x, x+2, x+4, and x+6, with x being the smallest of the four. twice the sum of the second and third can be written as 2(x+2+x+4)=4x+12 the sum of the first and fourth increased by 14 is x+x+6+14=2x+20 Then we can solve 4x+12=2x+20-->2x=8-->x=4 4
