Final answer:

To solve the simultaneous equations, manipulate one to match the coefficient of y in the other, subtract, simplify, isolate y, substitute back to find x, and then y. Finally, check the solution in the original equations.

Step-by-step explanation:

To solve the given simultaneous equations, we need to manipulate the equations algebraically to find the values of x and y. The given equations are:

  • 32x + 22y = 33 (Equation 1)
  • 44x - 24y = 6 (Equation 2)

Let's multiply Equation 1 by a number that will make the coefficients of y in both equations match in absolute value. In this instance, multiplying by 2 seems suitable:

  • 64x + 44y = 66 (Equation 3)

Now subtract Equation 2 from Equation 3:

  • (64x + 44y) - (44x - 24y) = 66 - 6
  • 20x + 68y = 60

Next, divide the entire equation by 4 to simplify:

  • 5x + 17y = 15 (Equation 4)

We can solve for y by isolating it in Equation 4:

  • 17y = 15 - 5x
  • y = (15 - 5x) / 17

Let's substitute this y back into Equation 1 or 2 to find x. After finding x, we can substitute it back into Equation 4 to find y. Remember to check your solutions in both original equations to confirm their correctness.
