Question

in elimination method, do we have to multiply the complete equation or just the term we want to be alike?

Answer 1

Hi friend, Here's the required answer:-

Yes you have to multiply the whole equation with a number. For example:-

2x-3y= 7 --------(1)
x+ 4y=4 ----------(2)

So multiply the Equation (2) with 2,

2x+8y = 4.

And now solve it by subtracting Equation (1) from (2).

Hope this helps you...
