If -7(x - 4), then -7x + 28

If m = -2, then 8m = -16.

10y = 10y

If 2x = 14, then x = 7.

If k = 3, then 3 = k

If -5x - 1= -11, then -5x = -10.

Given 3x + 1, if x = 5, then 3(5) + 1

If 6y = 24, then 6y - 3 = 24 - 3.

If 10a = 2b and 2b = c, then 10a = c

i need the property of equality for each of these
