Systems of Equations: E.g. 2x + 3y = 1 x
... We add the two equations with one of the variables having coefficients of the same magnitude but opposite sign (for example, one maybe 4x and the other โ4x) so we may eliminate one of the variables. If the two equations do not have any variables with coefficients of opposite sign, we multiply by the ...
