MultiStep EquationsIf you have `p` rows of 4 patches then you have `4cdot p` patches in total. Now if you add `y` patches to each row then you would `p cdot(4+y)=4p+py` patches in total. It's similar as counting...

MultiStep EquationsLet's first calculate `x`. Since difference between two consecutive terms is 4 it follows `3x4x=4` `2x=8=> x=4` So first three terms are: 4, `3cdot44=8`, `4+8=12` On the other hand we have...
