Question

3. Solve : 48x + 32y = 64
32x + 48y = 16

Answer 1

Answer:

y=-1 and x=2

Step-by-step explanation:

48x+32x = 64

32x+48y=16

dividing both equation by 16

we get

3x+2y=4

2x+3y=1

by multiplying 1st equation by 2 and second by 3 we get

6x+4y=8

6x+9y=3

subtracting 1 from 2 we get

5y=-5

y=-1

by putting the value of y in any of the equation we get

x=2
