Solve the following equation.
-3 = z + 4
A. z=1 *My answer*
B. z=-1
C. z=-7
D. z=7
hmmm
-3 = z + 4
-4 = 0 - 4
-------------- add
-7 = z + 0
Ohhh, I see, so it'd be -7
indeed :)
To solve the equation -3 = z + 4, we need to isolate the variable z.
First, let's get rid of the 4 on the right side of the equation by subtracting it from both sides:
-3 - 4 = z + 4 - 4
This simplifies to:
-7 = z
So the value of z that satisfies the equation is -7.
Therefore, the correct answer is C. z = -7.
