To solve the equation -4(z+12)=36 for z, we'll start by distributing the -4 to the terms inside the parentheses.
-4z - 48 = 36
Next, we'll isolate the z term by adding 48 to both sides of the equation.
-4z = 36 + 48
Simplifying the right side of the equation,
-4z = 84
Finally, we'll divide both sides of the equation by -4 to solve for z.
z = -84/-4
Simplifying the right side,
z = 21
Therefore, the solution to the equation when solving for z is:
A. 21
