What is the solution of the equation −8x + 13 = −19?
A. −3/4
B. 4
C. 3/4
D. −4
To solve the equation, −8x + 13 = −19, we need to get x by itself on one side of the equation.
First, subtract 13 from both sides of the equation:
−8x + 13 - 13 = −19 - 13
−8x = -32
Next, divide both sides of the equation by -8 to solve for x:
(-8x)/-8 = (-32)/-8
x = 4
Therefore, the solution to the equation −8x + 13 = −19 is x = 4, which corresponds to option B.
