Manual Operations on the Sides

**What**: Use ff to duplicate the manual ways of school teachings **Why**: To make sure you understand how to manipulate sides of an equation on your own. **How**: Simply try to duplicate what the teacher does to solve an equation by working the sides. **Time To Complete**: 6 hours

pts2 is your friend the Line! In 2D, any equation of the form a*x+b*y + c = 0 has solutions namely the x and y coordinates that satisfy the identity, namely lhs = rhs, line up along a fixed line specified by the three constants a, b and c.

hs = x-3;
rhs = 17*y+9;

lhs = lhs -9;
rhs = rhs -9;

lhs = lhs/17;
rhs = rhs/17;

show lhs also rhs;

save as trash;

**Output**
