Answer:

See below.

Step-by-step explanation:

1) Two equations are equivalent if they have the same solutions.

2) As long as two expressions [tex]a[/tex] and [tex]b[/tex] are equal, so [tex]a=b[/tex], adding the same value for both sides still makes the equation true, so

[tex]a = b[/tex]

[tex]a + c = b + c[/tex] is true.

3) As long as two expressions [tex]a[/tex] and [tex]b[/tex] are equal, so [tex]a=b[/tex], subtracting the same value for both sides still makes the equation true, so

[tex]a = b[/tex]

[tex]a - c = b - c[/tex] is true.
