The second equation can be 10x – 14y = –4 –10x + 14y + 4 = 0 10x + 14y + 4 = 0 –10x – 14y + 4 = 0 5 / 10Q.35 Two numbers are in the ratio 5 : 6. If 8 is subtracted from each of the numbers, the ratio becomes 4 : 5. Then the numbers are: 40, 48 40, 4 40, 8 4, 48 6 / 10Q.36 The solution of the equations x – y = 2 and x + y = 4 is: 3 and 1 3 and 2 3 and 3 3 and 4 7 / 10Q.37For which values of a and b, will the following pair of linear equations have infinitely many solutions?x + 2y = 1(a – b)x + (a + b)y = a + b – 2 a = 3 and b = 1 a = 3 and b = 11 a = 3 and b = 111 a = 3 and b = 1111 8 / 10Q.38 The father’s age is six times his son’s age.
