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

Respuesta :

The answer is 7*2+14k=28 
k is 1

Answer:

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

Step-by-step 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

[tex]k = \frac{14}{14}[/tex]

k = 1

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