Answer 1

sorry but take a look at this

For unique solution a1/a2 should not be equal to b1/b2 ...so 4/k =1/1

if we cross multiply them we get k is equal to 4...

Bt as the question says it is a unique solution so we'll write it as k should bt be equal to 4

hope it helps you

and your hand wrighting is quite nice
