State the property that justifies the statement: If 4x + 9 = 15 and X=2y + 1,
GREYUIT [131]

Answer:

Substitution property of equality

Step-by-step explanation:

Given

4x + 9 = 15 and x = 2y + 1

Then

4(2y + 1) + 9 = 15

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If a = b then b = a

In other words, both can replace one another.

So if x = 2y + 1, then 2y + 1 can be substituted for x in 4x + 9 = 15

So:

4x + 9 = 15  becomes

4(2y + 1) + 9 = 15

<em>Hence, it is substitution property of equality</em>
