Solve the simultaneous equations for x and y: 2x - 3y + 4 = 0 , x - 2y + 1 = 0.

Simultaneous equations can be solved either by substitution or elimination. Solving this by elimination:2x - 3y + 4 = 0 (1)x - 2y + 1 = 0 (2)To eliminate x, we can multiply both sides of the second equation by 2:2x - 4y + 2 = 0 (3)By subtracting (1) from (3) we find that y = -2. Substituting this into (2) gives x = -1 + 2(-2) = -5.
