Equation 1: x-2y=3Equation 2: x²+2y²=27The easiest way to do this is to put one of these equations into the other, by rearranging for either x or y. Because there are no squares to d...

A matrix is a representation of a linear map with respect to any basis of vectors of our choice. We often deal with matrices with respect to the standard cartesian basis, (1,0,0) (0,1,0) (0,0,1), but we c...

The first step is to rearrange for x: we have x=2y-3now we can plug this into the equation of the ellipse: y^2+2(2y-3)^2=39y^2-24y+15 = 0we can use the quadratic formula to solve this equation:y = (24+-sq...

When contemplating whether to use Ser or Estar, I find the best expression to help you remember is 'for how you feel and where you are always use Estar'!Despite both verbs meaning 'to be', ser is used wh...
