Answer 1

Step-by-step explanation:

you have to subtract sec eqn frm first

so x gets eliminated and u can easily find the value of y

then substitute in any eqn to get the value of x

Answer 2

Step-by-step explanation:

1. $(3x + 8y = 43) - (3x - 7y = 13) \\ 3x + 8y - 3x + 7y = 43 - 17 \\ y = 26 \\ after \: that \: put \: the \: value \: of \: y \: in \: any \: equation \: and \: find \: the \: value \: of \: x$
