solve the following system of equations 4x3y5z 23 2x5y3z13

solve the following system of equations :

4x-3y+5z =23

2x-5y-3z=13

-4x-6y+7z= 7

Solution

Given equations

4x – 3y +5z = 23--------1

2x -5y – 3z = 13----------2

-4x – 6y +7z = 7-----------3

By solving ` the three equations in calculator we get

X = 3    Y = -2     Z = 1
