We are asked to solve a system of linear equations via the elimination method.
3 x - 2 y = 0
2 x + y = 7
in order to use elimination, we look into finding appropriat factors to use to multiply one (or both) of the equations, so that one of the variables can be eliminated just by adding the equations term by term, thus leaving us with an equation that contains only one unknown, and which we can easily solve.
Looking at our system, we select to multiply the second equation by "2",and that way, eliminate the term in
