Question

solve 6x = 30, Keith divided both sides of the equation by 6. Which property justifies this step A. multiplication property of equality B. commutative property of multiplication C. Distribute property D. division property of equality

Answer 1

it is the division property of equality

Answer 2

D. division property of equality

Explanation:

Multiplication property of equality states that an equation does not change after multiplying both sides of an equation by the same number.

Commutative property of multiplication states that the product of a and b can be written the product of b and a.

Distribute property : a number is distributed inside a bracket,

Division property of equality states that an equation does not change after dividing both sides of an equation by the same number.

Here, the given equation,

`6x=30`

By division property of equality,

`(6x)/(6)=(30)/(6)`
