5+2x+8
To solve for x, we can first set this expression equal to 0. Doing this makes the expression a solvable equation.
5+2x+8=0
Add 5 and 8.
13+2x=0
Then, subtract 13 so that the x is on one side of the equation.
2x=-13
Dive both sides of the equation by 2 to get x by itself.
2x/2=-13/2
That gives us...
x=-13/2

How do you put 2x-5-4x plus 8 in simplest terms?
2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3
2x plus 5 equals plus 13?
-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.
3x plus 8 equals 2x plus 5 What does X equal?
3x+8 = 2x+5 Subtract 2x from both sides: x+8 = 5 Subtract 8 from both sides: x = -3
What is the solution of -2x plus 5 equals 8 and 2x plus 2x equals 6?
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
Twice a number plus 5 is negative three?
2x + 5 = -3 2x = -8 x = -8/2 x = -4
