To solve the equation -4(z+12)=36, we can start by distributing the -4 to both terms inside the parentheses:
-4z - 4(12) = 36
Next, simplify the expression by performing the multiplication:
-4z - 48 = 36
Now, we can isolate the variable z by adding 48 to both sides of the equation:
-4z = 36 + 48
-4z = 84
Finally, 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 is z = -21.
