Q.1
a) Solve the following system of equations using Matrix Inversion method
3x + 2y + 4z = 7
2x + y + z = 7
x + 3y + 5z = 2​

Answer 1

Step-by-step explanation:

A= 3 2 4

2 1 1

1 3 5

X= x

y

z

B= 7

7

2

X=A^-1 B ___(i)

next find A^-1

then put the values of X , A^-1 and B in eqiation (i)

then multiply A^-1 and B then values of x,y,z and found
