Equation step-by-step:

-(3z + 4) = 6z - 3(3z + 2) → we break down the () with the distributive property

-3z - 4 = 6z - 9z - 6 → we take -4 to the right side of the equation

-3z = 6z - 9z - 6 + 4 → we solve for - 6 + 4

-3z = 6z - 9z - 2 → we solve 6z - 9z

-3z = -3z - 2 → we take -3z to the left side of the equation

-3z + 3z = -2 → we solve for - 3z - 3z

0 = -2 → final answer. There is no solution to this equation, it's false.

Hope it helped,

-3z - 4 = 6z - 9z - 6

-3z - 4 = -3z -6

So the reciprocal of 14.3% = 100/14.3 = 1000/143, and then you can do 1000/143 * 278, which would equal <span>1944.05594406 (Cool and hard muiltiplication that took me like 2 minutes). To make it to the nearest tenth, it would be 1944.1
