if left side and right side of an equation are equal then if we divide if by same number then it will not change for eg 2(x+1):-50

then x:-24

if we divide it by 2 both the side then

2(x+1)/2:-50/2

x+1:-25

x:-25-1:-24

in both the cases ans are same so if we divide both side of the equation by nonzero number the value doesnt change.

The definition of division property of equality?

I think its a property in which both sides of an equation are equal either by adding, subtracting, multiplication, or division.


Should the number that multiplies each side of the equation be nonzero when using multiplication property?

Yes, it should be non-zero; if you multiply both sides by zero you wipe out the equation.


What is the number if twenty times the square of a nonzero number is equal to 15 times the number?

Let the number be 'n'. Then, 20n2 = 15n.......divide throughout by 5 4n2 = 3n...................divide both sides by n 4n = 3 n = 3/4


is this statement true or falseThe Multiplication Property of Equality states that an equation remains true if you divide both sides of the equation by the same number.?

false


What is Division Property of Equations?

You can divide both sides of an equation by any non-zero number and not affect its validity.


Can large quantities can always be added or subtracted from both sides of an equation?

The size of the quantities involved doesn't matter. As long as you add or subtract (or divide or multiply) the same number to or from both sides of the equation, then the two sides remain equal.


How can you define the division property of equality?

If you divide both sides of an equation by some non-zero number then they remain the same. The non-zero number part is added because we cannot divide by zero. Example: 2x+2=10 Divide by sides by 2 and we have x+1=5 which is the same as the original equation. The solution to both is x=4


What do you have to do to get a variable alone?

A) Divide both sides of the equation by 4.


How do you solve 2x equals 32 using square roots?

You don't need square roots for this, and there is no use for them in this context.

Who do you Rearrange equations?

The basic principle is that (with some caveats for certain operations) you can apply the SAME operation to both sides of an equation. For instance, you can add the same number to both sides, divide both sides by the same number (watching out that you don't accidentally divide by zero), take the square root on both sides, etc.

If 4n equals 3.60 then what is the value of n?

Beginning with 4n = 3.60, divide both sides of the equation by 4 to get 4n/4 = 3.60/4. Carrying out the division we get n = 0.9, the answer. You can multiply or divide both sides of any equation by the same number to help you isolate the value for which you wish to solve. The equation remains true whenever the same factor is applied to all terms in both sides. (Exception: cannot divide by zero.)
