Question

Solve for matrices
a and b where
2a+b=(3 -4
2 7)


a-2b =(4 3
1 1)

​

Answer 1

1. 2a+b=(3-4×27)
2. a-2b=(4-3×11)

We have given two equation

solve 2nd equation and find a value in b form then put a value in 1st equation then we find b value then b value put in any equation we have find value a

then a value is -239/5

and b value is -47/5
