WebbSolve the simultaneous linear equations 2x +y = 7 3x −y = 8 2 x + y = 7 3 x − y = 8 Solution Rearranging the two equations into the form y = ax+b y = a x + b gives: y =−2x +7 y = 3x −8 y = − 2 x + 7 y = 3 x − 8 The lines have different slopes, so there is one unique solution. We will now find it using the elimination method.
