Question

Use the substitution property of equality to complete the following statement if y=3 and 8x+y=12,then_

Answer 1

Answer:

The answer is D) 8x+3=12

Answer 2

Answer:

The answer is D) $8x+3=12$

Step-by-step explanation:

In order to determine the correct option, we have to know about the substitution property.

The substitution property is when we replace the variable of the equation by a number. For example:

Given

$x+y=12\\x=3\\\\3+y=12\\y=12-3\\y=9$

In this example, we applied the substitution property replacing the "x" variable by 3.

For this case:

$8x+y=12\\y=3\\\\8x+3=12$

So, the final expression is matching with the D) option.

Finally, the correct answer is D) $8x+3=12$
