Solution of 3 linear equations fast method

Answer 1

I m sorry to tell you but there are no short cuts to solve 3 variables with 3 equations , but practicing it many times will make you faster to solve the equations.

First of all you need to substitute a variable in
an equation and the do the rest things lets go with an example:

1)ax+by=c

2)dx+ez=f

3)gy+hz=i

here x,y,z are variables and the rest are constant values

first of all we will take equations 1 and 2

through equation 1 we could analyse x=(c-by )/a

now substitute this value of x in equation 2 and now you have equations 2 and 3 with only variables y and z. Its easy to solve them now and later you get value of y and z you could easily get value of x by substituting ,

I hope you are now much familiar, practice and you would master this .
