what do you mean by dividing them equally? average????maihuna wrote:such Q requires dividing the two sides equally and substracting the half of that from x
4-(-2) = 6
6/2 = 3
so each side requires 3: -2-1<x-1<4-1 or -3<x-1<3 or |x-1|<3
The numerical values on either side of the modulus needs to be same, albeit with opposite sign, i.e -3<x<3, so fins the range of those number and divide them by 2 to get the equal no, and then suitably substract it from the mod vsar...hope it clarifies...shibal wrote:what do you mean by dividing them equally? average????maihuna wrote:such Q requires dividing the two sides equally and substracting the half of that from x
