To solve for z, we need to isolate the variable on one side of the equation.
First, let's subtract 4 from both sides of the equation:
-5z + 4 - 4 = 15 - 4
-5z = 11
Next, divide both sides of the equation by -5 to solve for z:
-5z / -5 = 11 / -5
z = -11/5
Therefore, the solution to the equation -5z + 4 = 15 is z = -11/5.
-5z+4=15
