implifying
4z + -15 = 4z + 11
Reorder the terms:
-15 + 4z = 4z + 11
Reorder the terms:
-15 + 4z = 11 + 4z
Add '-4z' to each side of the equation.
-15 + 4z + -4z = 11 + 4z + -4z
Combine like terms: 4z + -4z = 0
-15 + 0 = 11 + 4z + -4z
-15 = 11 + 4z + -4z
Combine like terms: 4z + -4z = 0
-15 = 11 + 0
-15 = 11
Solving
-15 = 11
