Question

of equations using substitution\
8.\
$x + y = 8$\
$3x + 2y = 8$

Explanation:

Step1: Isolate $x$ from first equation

$x = 8 - y$

Step2: Substitute $x$ into second equation

$3(8 - y) + 2y = 8$

Step3: Simplify to solve for $y$

$24 - 3y + 2y = 8$
$24 - y = 8$
$-y = 8 - 24$
$-y = -16$
$y = 16$

Step4: Substitute $y$ back to find $x$

$x = 8 - 16$
$x = -8$

Answer:

$x=-8$, $y=16$
