Alberto uses the steps below to solve the equation
Which justifies Step 6 of his work?
3* - 3 =
the addition property of equality
the identity property of addition
the multiplication property of equality
the identity property of multiplication
Step 1:
x - 3 + 3 = 7 + 3
Step 2:=x + 0 = 10
Step 3:
x =
Step 4: 2(_)* = 2(10)
Step 5: 1x = 20
Step 6: x = 20

Answer 1

I gotcha bud, the answer is 4. the identity property of multiplication

I hope this helped. Have a nice day, make sure to take care of yourself. You're loved <3

Answer 2

The identity property of multiplication

Explanation:

If a, b and c are any real numbers,

By addition property of equality,

a = b ⇒ a + c = b + c,

By identity property of addition,

a + 0 = a,

By multiplication property of equality,

a = b ⇒ a × c = b × c,

By identity property of multiplication,

a × 1 = a

Thus, it is clear that,

'The identity property of multiplication' justifies Step 6 .
