Question

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

4x = 5
X + 5 = -4
8/X= 1
(x + 5)(4x - 1) = 0

Answer 1

Explanation:

I would probably say C which is 8/X= 1.

The first one uses the division property of equality.

The second uses the subtraction property of equality.

The third uses multiplication property of equality, which basically means mulitplying both sides of an equation by the same quantity.

The last one does not follow any property that I am aware of or am acquainted with.

Answer 2

8/X= 1

Explanation:

"8/X= 1" requires the multiplication property of equality for 'x' to get solved.

`(8)/(x)=1\\\\(8)/(x)*x=1*x \leftarrow\text{Multiplication Property of Equality}\\8 = x \\\\\boxed{x=8}`
