3x-5y-4=0 and 9x= 2y+7

1.	3x-5y-4=0 and 9x= 2y+7
Answer» 3X - 5Y = 4----------(1)9X - 2Y = 7-------------(2)From EQUATION (1) we get,3X - 5Y = 43X = 4+5YX = 4+5Y/3 -------------(3)Putting the value of X in equation (2)9X - 2Y = 79 × (4+5Y/3) - 2Y = 73(4+5Y) - 2Y = 712 + 15Y - 2Y = 713Y = 7 -1213Y = -5Y = -5/13Putting the value of X in equation (3)X = 4+5Y/3 => 3 + 5 × -5/13 = 3 - 25/13 /3X = 39 - 25/13/3 = 14/13/3 => 14/13 × 1/3 => 14/9
