What is the value of z in the equation 2(4z − 9 − 7) = 166 − 46?

19
21
26
34

2(4z-9-7)=166-46 well, perentices (however u spell these things) first, -9-7 = -16 so 2(4z-16)=166-46 and distributive property so 8z-32=166-46, 166-46 = 120, so 8z-32=120, add 32 to both sides, which would be 8z=152 divide both by 8, z=19
