Consider the steps to simplify the expression. which property is used to reach step 3? expression: -4 3/7 + 7 + (-3 4/7 ) step 1: = -4 3/7+(-3 4/7) + 7 step 2: = -4 + (-3/7) + (-3) + (-4/7) + 7 step 3: = -4 + (-3/7) + (-4/7) + (-3) + 7 step 4: = -4 + (-1) + (-3) + 7 step 5: = -8 + 7 step 6: = -1 a) the associate property of addition. b) the commutative property of addition. c) the opposite of a sum is the sum of its opposites. d) subtracting a number is the same as adding its inverse.

Step-by-step explanation:

Given expression :

Step 1: = -4 3/7+(-3 4/7) + 7

Step 2: = -4 + (-3/7) + (-3) + (-4/7) + 7

Step 3: = -4 + (-3/7) + (-4/7) + (-3) + 7

Step 4: = -4 + (-1) + (-3) + 7

Step 5: = -8 + 7

Step 6: = -1

In 3rd step they just swap the positions of (-4/7) and (-3) to bring the like fractions with common denominator together.

Swapping the numbers is the Commutative Property of Addition.
