# 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.
