NettetQ.4: Solve the following pair of linear equations by the substitution method. (i) x + y = 14 x – y = 4 (ii) 3x – y = 3 9x – 3y = 9 Solution: (i) Given, x + y = 14 and x – y = 4 are the two equations. From 1st equation, we get, x = 14 – y Now, put the value of x in second equation to get, (14 – y) – y = 4 14 – 2y = 4 2y = 10 Or y = 5 NettetSolving these types of problems takes on the general pattern of the following four steps. 1.)
