Give the property that justifies each step.
frosja888 [35]

Answer:

Please check the explanation below.

Step-by-step explanation:

Some of the properties are defined as:

  • <em>Distributive property</em>

a(b+c) = ab+ac

For example,

suppose a=3, b=4, c=5

3(4+5) = 3(4) + 3(5)

3(9) = 12+15

27 = 27

  • <em>Subtraction property of Equality</em>

if (a=b), then a-c = b-c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a-c = b-c ⇒ 2-5 = 2- 5 ⇒ -3 = -3

  • <em>Addition property of Equality</em>

if (a=b), then a+c = b+c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a+c = b+c ⇒ 2+3 = 2+3  ⇒ 5 = 5

  • <em>Multiplicative property of Equality</em>

if (a=b), then a×c = b×c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a×c = b×c ⇒ 2×5 = 2 × 5  ⇒ 10 = 10

  • <em>Division property of Equality</em>

if (a=b), then a÷c = b÷c

For example,

suppose a=2, b=2, c=5

if a = b ⇒ 2 = 2

then a÷c = b÷c ⇒ 2÷5 = 2 ÷ 3  ⇒ 2/5 = 2/5

Let us solve the given equation using the above properties.

7n-16=47                     Given

7n-16+16=47+16   1) Addtion property of Equality ∵ if (a=b), then a+c = b+c

7n=63                  2) simplify

n = 9                    3) Division property of Equality ∵ if (a=b), then a÷c = b÷c
