Question

4x+3y = 50oo, xty = 750​

Answer 1

Step-by-step explanation:

4x+3y = 5000 ---(1)

x+y = 750 ----(2)

multiply. eq.2 by 3 and then subtract eq.1 and 2

4x+3y = 5000

3x+3y= 2250

- - -

––––––––——————

x = 2750

now put the value of x in eq.2 , we get ,

x+y = 2250

2750 + y = 2250

y = 2250 - 2750

y = -500

Hence ,

x = 2750

y = -500
