solve using determinants

Question

3x+4y+z=10

2x-3y-5z+9=0

x+2y-z=6   solve simultaneous equations by using determinants

Answer 1

Given equations are 3x+4y+z = 10

2x-3y-5z+9 = 0

x+2y-z = 6

Here to solve the equations we use cramers method.

Rewrite the equations into matrix form AX = B

A is coefficient matrix, B is constant matrix and X is variable matrix.

Solution x = -13/17, y = 54/17, z = -7/17.
