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:
[tex]a=b[/tex]
We can divide both sides by "c" (a non-zero constant) and the remaining answer will be the same.
So,
[tex]\frac{a}{c}=\frac{b}{c}[/tex]
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.
[tex]5x=30[/tex]
