HI!!

misty1212 · Answer

combine like terms first

misty1212 · Answer

then divide both sides by 2

hi can you help!

misty1212 · Answer

$$2(4z-12)=124$$ is a start

misty1212 · Answer

that is what you get when you do the arithmetic, $-6-6=-12$ and $170-46=124$

misty1212 · Answer

then divide by 2 and you get 
$$4z-12=124$$ two more steps

misty1212 · Answer

a) add $12$ to both sides, then 
b) divide both sides by $4$

	12.5
	15.5
	16.5
	18.5
evaluate the expression first
2(4z-6-6)=170-46
2(4z-12)=170-46
8z-24=124
8z=124+24
8z=148
Divide both sides  by 8...we come up this
z=18.5
