What is answer to x+10=-13 what does x equal

Answers

x + 10 = -13
-13 - 10 = x
-23 = x

CHECK

-23 + 10 = -13
-13 = -13!

x + 10 = -13 (original problem)
-10 -10 (subtract 10 from each side)
The 10 - 10 equals 0 so it cancels out of the problem.
x = -23 <- (-13 - 10 = -23)

Answer: W= -4/3=-1.33333

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

w*(-3)-(-3+7)=0

Pull out like factors : -3w - 4 = -1 • (3w + 4)

Solve : -3w-4 = 0

Add 4 to both sides of the equation :

-3w = 4

Multiply both sides of the equation by (-1) : 3w = -4

w = -4/3 = -1.333
