Can we take k = -28 to +28 in last question... which gives 57 solutions... ??????

@arskandan Жыл бұрын

in the last question zero should come twice because the equations are different as on the positive side we have 6 + 7k and for initial value we will put the value of k as 0. similarly for the negative side the equation is -1 -7k when we put 0 we will get -1. hence the ans is correct 57 solutions.

@Kams_15_Official 11 ай бұрын

Values of x and y would be solutions and not the values of k. So the answer is 57 only.

Both K's are different K's dude. One for the positive side, one for the negative side. You can clearly see that there are 2 different equations of K. So No need to subtract 1.

@bipulkumar5070 4 жыл бұрын

I am slightly confused about the increase and decrease pattern of solution series of x and y. For example, If I express the equation as 7y = 115 - 3x , does it mean that the solution series of x would be an AP with CD of +7 ? Is sign of the equation a reliable method to decide this or should this be determined by observation (hit and trial)

@chinmaysomani5387 3 жыл бұрын

Signs can be determined by simple observation.

@saikatkundu1149 3 жыл бұрын

we generally keep the small coeff variable in the LHS since that variable has c.d of the opp variable which is larger. But the value of both the variable increase and decrease by the C.D on both sides of the number lines just like in the last example, but for negative solutions we just consider the changes to get non negative solutions

The 0 he counted is not the numbers from progression.. its k's value. I.e in the positive side there are 0 to 27 values of k thats satisfies hence altogether 28 values, when k is 0 there the actual value of 'a' is 6 (7k+6 where k is 0) and in the negetive side of the progression when k is 0 the value is -1
