Question

The Substitution Property of Equality allows you to say that if 7j + 14k = 28, and j = 2, then _____.

7(j + 2k) = 28


k = 2


7 ● 2 + 14k = 28


28 = 14k + 7j

Answer 1

The answer is 7*2+14k=28
k is 1

Answer 2

The Substitution Property of Equality allows you to say that if 7j + 14k = 28, and j = 2, then k = 1 .

Explanation:

As the expression is given in the question be as follow .

7j + 14k = 28

As given the value of j = 2 .

Put the value of j in the equation 7j + 14k = 28 .

7 × 2 + 14k = 28

14 + 14k = 28

14k = 28 - 14

14k = 14

`k = (14)/(14)`

k = 1

Therefore the Substitution Property of Equality allows you to say that if 7j + 14k = 28, and j = 2, then k = 1 .
