RD Sharma Class 10 Solutions Chapter 3 Pair of Linear Equations in Two Variables MCQS Solve the following systems of equations graphically Question 1 x y = 3 2x 5y = 12 (CBSE 1997) Solution x y = 3 => x = 3 – y Substituting some different values of y, we get the corresponding values of x as shown belowGet stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us! see below Graphically the roots are where the graph crosses the xaxis that is when y=0 graph{x^28x16 374, 1404, 256, 633} As can be seen from the graph it touches the xaxis at one point only x=4 Algebraically we could use factorising, completing the square or the formula look for factorising first x^28x=16=0 (x4)^2=(x4)(x4)=0 x4=0=>x=4 the
