Answer ! which property was used to write the equation in step 2?

Distributive property:

a(b - c) = ab - ac

5(x - 7) = 55

(5)(x) - (5)(7) = 55

5x - 35=55

Distributive property

Step-by-step explanation:

Distributive property clearly states that if a is multiplied to (b + c) then we get (ab + ac).

Or a(b + c) = ab + ac

Now we see the second step of the question

Step 1 : 5(x - 7) = 55

Step 2 5x - 35 = 55 [Distributive property]

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
