consider the sequence of steps to solve the equation:
5(x - 3) =
7x
2

step 1 ⇒ 10(x - 3) = 7x
step 2 ⇒ 10x - 30 = 7x
step 3 ⇒ 3x - 30 = 0
step 4 ⇒ 3x = 30
step 5 ⇒ x = 10

identify the property of equality which gets us from step 3 to step 4.
a) division property
b) addition property
c) subtraction property
d) multiplication property
