text: slve use substitution methd x-5y=2 & 7y-3x=10 the ordrd pair solution is? you all r saving me x-5y=2.......eq 1  7y-3x=10.......eq 2 consider eq 1 x - 5y = 2 x = 2 + 5y substitute the derived value of 'x' in eq 2 7y-3x=10 7y - 3(2 + 5y) = 10 7y - 6 - 15y = 10 -8y = 10 + 6 -8y = 16 y = 16/-8 y = -2 substitute the value of 'y' in eq 1 x-5y=2 x - 5(-2) = 2 x + 10 = 2 x = 2-10 x = -8 the ordered pair is : (-8,-2)
