The correct boxes to the complete pairs are,
12 - 1/2r → (-8 - r) + (2r - 4)
r - 13/6 → (7r - 3/2) - (2/3 + 6r)
13r + 20 → (6r + 7) + (13 + 7r)
-12 + r → (-8 - r) + (2r - 4)
What is simplified expression?
Writing a similar expression devoid of similar terms is what is meant by the expression "simplify." In other words, we will rewrite the expression using the fewest number of terms.
Consider, the given expressions
(1) (6r + 7) + (13 + 7r)
Simplifying this,
6r + 7 + 13 + 7r
13r + 20
(2) (13 - 3/2r) - (1 - r)
Simplifying this,
13 - 3/2r - 1 + r
12 - 1/2r
(3) (-8 - r) + (2r - 4)
Simplifying this,
-8 - r + 2r - 4
-12 + r
(4) (7r - 3/2) - (2/3 + 6r)
Simplifying this,
7r - 3/2 - 2/3 - 6r
r - 13/6
Hence, the correct boxes to the complete pairs are,
12 - 1/2r → (-8 - r) + (2r - 4)
r - 13/6 → (7r - 3/2) - (2/3 + 6r)
13r + 20 → (6r + 7) + (13 + 7r)
-12 + r → (-8 - r) + (2r - 4)
