Work Step by Step
a)
$9.1x-y=-295$
$14x-y=-262$
$9.1x-y=-295$
$-1*(9.1x-y=-295)$
$-9.1x+y=295$
$14x-y=-262$
$-9.1x+y=295$
$-9.1x+y+(14x-y)=295-262$
$4.9x=33$
$4.9x/4.9=33/4.9$
$x = 6.73$
$14x-y=-262$
$14*6.73-y=-262$
$94.22-y=-262$
$356.22-y=0$
$356.22=y$
$14x-y=-262$
$14*7-y=-262$
$98-y=-262$
$360-y=0$
$360=y$
