Question

Solve the following systems of equations:
x+2y =3/2
2x+y =3/2

Answer 1

The given system of equation is

Let us eliminate y from the given equations. The Coefficients of y in the given equations are 2 and 1 respectively. The L.C.M of 2 and 1 is 2. So, we make the coefficient of y equal to 2 in the two equations.

Multiplying (i) by 1 and (ii) by 2, we get

Hence, solution of the given system of equation is
