Question

Chapter = Linnear simulation equation. Please answer it fast whose answer is correct I give it brainlieast answer​

Answer 1

Answer:

4x - 3y = 18 -> (i)

- 5x + 4y = - 7 -> (ii)

Multiplying eqn (i) by 4 and (ii) by 3

:. 16x - 12y = 72 -> (iii)

:. -15x + 12 y = - 21 -> (iv)

Adding equation (iii) and (iv)

16x - 12y = 72

-15x + 12y = -21

----------------------

:. x = 51

Substituting x = 51 in equation (i)

i.e. 4x - 3y = 18

:. 4(51) - 3y = 18

204 - 3y = 18

- 3y = 18 - 204

- 3y = - 186

- y = -186

3

- y = - 62

:. y = 62
