0.01x - 0.3y = 1 if multiplied by 100, this appears without fractions as
x - 30y = 100, or x = 30y + 100
y = 0.1x - 2, if mult. by 10, becomes 10y = x - 20
If you want to go a step or two further and solve this, subst. x = 30y + 100 into the 2nd equation: 10y = (30y + 100) - 20
-20y = 80, and y = -4.
