So, if may has two more nickles then pennies and assuming  that both their values add up to 30 we can begin by  30/2 and because there are two less pennies, and we are solving for the number of pennies (x) we can write this as 30/2-2=x changing the subject of the formula to 30 will give us 2(x+2)=30
