Answer:

#1

[tex]{ \tt{a - x = y}} \\ \\ { \boxed{ \tt{x = a - y}}}[/tex]

#2

[tex]{ \tt{m = k - x}} \\ \\ { \boxed{ \tt{x = k - m}}}[/tex]

#3

[tex]{ \tt{k - {t}^{2}x = m }} \\ { \tt{ {t}^{2} x = k - m}} \\ \\ { \boxed{ \tt{x = \frac{k - m}{ {t}^{2} } }}}[/tex]

Step-by-step explanation:

1) a-x=y

a-a-x=y-a

-x=y-a

x= -(y-a)

2) m=k-x

-x=m-k

x= -(m-k)
