Question

x + 9 = 0 , 2y - 12 = 0

Answer 1

Step-by-step explanation:

x+9=0

=x=0-9

=x=-9

2y-12=0

=2y=12

y=12/2

y=6

Answer 2

${ \boxed{ \bold \red{A}}}{ \boxed{ \bold \green{N}}}{ \boxed{ \bold \blue{S}}}{ \boxed{{{ \bold{W}}}}}{ \boxed {\bold \pink{E}}}{ \boxed {\bold \purple{R}}}$

$x + 9 = 0$

$x + 9 - 9 = 0 - 9$

$x = - 9$

$2y - 12 = 0$

$2y - 12 + 12 = 0 + 12$

$2y = 12$

$\frac{2y}{2} = \frac{12}{2}$

$y = 6$
