MultiStep Equations`5x^27x11=0` We know that: `x_1 + x_2= 7/5` (1) and `x_1 xx x_2=11/5` (2) From (1): `1+x_1+x_2= 12/5` So: `1+x_1=12/5x_2` `1+x_2=12/5x_1` Then:...

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...
