1) 5x - 6y = -32 --> equation 1 3x + 6y = 48 --> equation 2 eliminating y from both of the equations and adding the rest of the terms we get, 8x = 16 dividing 8 on both sides x = 2 Substituting the value of x in equation 1 5(2) - 6y = -32 10 - 6y = -32 -6y = -12 ( dividing both sides by -6) y = 2
2) -3x - 3y = 9 ---> equation 1 3x - 4y = 5 --> equation 2 eliminating x from both equations and adding the rest of the terms we get, -7y = 14 ( dividing both sides by -7 ) y = -2 Substituting the value of y in the equation 1 -3x - 3(-2) =9 -3x + 6 = 9 (subtracting both sides by -6) -3x = 3 x = -1
