Lesson 6 of 20 · about 15 min
Systems of equations
Two equations, two unknowns. You can picture them as two lines that cross, or as two arrows that have to mix into a target. You'll tweak equations until their lines meet at a point, run parallel forever, or lie on top of each other, and find out why every system has exactly one, zero or infinitely many solutions, never two.
