$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$7 - y = 6$

$➺ \: - y = 6 - 7$

$➺ \: - y = - 1$

$➺ \: y = 1$

Therefore the value of $y$ is 1.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$7 - y = 6$

$➼ \: 7 - 1 = 6$

$➼ \: 6 = 6$

➼ L. H. S. = R. H. S.

Hence verified.
