Given data:

The two given equations are

  • 3x + 4y = 10
  • 4x - 3y = 5

To find:

  • whether the given pair of equations represents consistent or inconsistent system of equations
  • if consistent, the solution

Step-by-step explanation:

The given equations are

  • 3x + 4y = 10 . . . . . (1)
  • 4x - 3y = 5 . . . . . (2)

We see that, 3/4 ≠ 4/(- 3). Thus the system of equations is consistent.

We can get a solution. Let us try with method of elimination.

Multiply equation (1) by 4 and equation (2) by 3. We get

  • 12x + 16y = 40
  • 12x - 9y = 15

On subtraction, we get

  • 25y = 25, i.e., y = 1

Putting y = 1 in (1), we get

  • 3x + 4 = 10
  • or, 3x = 6
  • or, x = 2

Therefore the required solution is x = 2, y = 1.
