Question

2 x minus 3 Y is equals to 4; 3Y - x is equal to 4

Answer 1

Hii friend,

2X-3Y = 4.......(1)

3Y-X = 4.........(2)

From equation (1) we get,

2X-3Y = 4

2X = 4+3Y

X = 4+3Y/2.....(3)

Putting the value of X in equation (2)

3Y-X = 4

-X +3Y = 4

-(4+3Y/2) + 3Y = 4

-4-3Y/2 + 3Y = 4

-4-3Y + 6Y = 8

3Y = 8+4

Y = 12/3

Y = 4

Putting the value of Y in equation (3)

X = 4+3Y/2

X = 4+3×4/2 = 4+12/2 = 14/2 = 7


HOPE IT WILL HELP YOU..... :-)
