Question

Best way to start off solving 4x+y=3
5x–2y=7 by elimination.

Answer 1

..By eliminating the y variable.

Answer 2

Multiply first equation by 2 and tell me what you get??

Answer 3

See, when eliminating a particular value like y in this case, we always try to make the coefficients of y in both the equations equal..

In first equation, coefficient of y is 1
In second it is -2

So, multiply first equation by 2...

Tell me what you get after multiplying??

Answer 4

It is the best way to start this problem by multiplying 2 with both sides of the first equation and then adding them you will get x...

Try it..
