 4. Addition-Substration Method Solve linear equations 7Y+2X-11=0 and 3X-Y-5=0 using Addition-Substriaction Method2X+7Y-11 = 0 ->(i)3X-Y-5 = 0 ->(ii)Adding Equation (i) and (ii), we get5X+6Y-16 = 05X+6Y-16 = 0 ->(iii) (On simplifying)Subtracting Equation (ii) from (i), we get-X+8Y-6 = 0X-8Y+6 = 0 ->(iv) (On simplifying)5X+6Y = 16 ->(1)X-8Y = -6 ->(2)Eqn.(1) xx 1 => 5X+6Y = 16Eqn.(2) xx 5 => 5X-40Y = -30Substracting => 46Y = 46=> Y = 46 / 46=> Y = 1Putting Y = 1 in Eqn. (2), we haveX-8(1) = -6=> X = -6+8=> X = 2=> X = 2:. X = 2" and "Y = 1
