To solve for z you need to get it by itself and have the other half of the equal sign simplified.
42=-7 (z-3)
42=-7z+21 (you would distribute the - 7 through the parentheses.)
21=-7z (you would then subtract 21 from both sides)
-3=z (last your would divide - 7 to both sides to get z by itself)
z=-3
