Question

The division property of equality could be used to solve which of the following equations

Answer 1

The division property of equality states that dividing both sides of an equation by the same non-zero constant doesn't change the equation.

If we have an equation:

`a=b`

We can divide both sides by "c" (a non-zero constant) and the remaining answer will be the same.

So,

`(a)/(c)=(b)/(c)`

Let's look at the options:

Option 1:

We can divide by 5 on both sides to solve for x.

Option 2:

We can subtract 3 from both sides to solve for x.

Option 3:

We multiply the two terms out and do middle term factorization to solve for x.

Option 4:

We cross multiply 4 and 16 to solve for x.

Thus, Option 1 shows the usage of division property of equality.

So,

we can say option 1 is the correct answer.

`5x=30`
