Q. 4 D4.6( 9 Votes )

Let us solve the following linear simultaneous equations in two variables by the method of elimination:




Answer :

Rewriting the above equation as.


3x + 2y = 48 (i)


5x – 12y = - 12 (ii)


In this problem, we will eliminate ‘y’ from both the equations!


Multiplying equation (i) with 6, we have



x = 12


Putting the value of y in equation(i)


We have y = 1/2(48 - 3x) or y = 6.


Hence the solution of the linear equation is x = 12 and y = 6.
