-8= -2(z+7)                  Equation

\dfrac{-8}{-2} =z+7

 
      Divide \ both \ sides \ by \ -2
 
<span>\dfrac{8}{2} =z+7  
</span>
4=z+7&#10;&#10; &#10; 

4-7=z            Subtract \ 7 \ from \ both \ sides

z=-3              Solution

To get the percent of increase, we will follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6
2- divide the difference from step one by the original number (the number before the increase) and then multiply the quotient by 100 to get the percent as follows:
% of increase = (0.6 / 1.2) * 100 = 50%

Based on the above calculations, the percent of increase in the amount of iron is 50%
