Question

Which method should be used to solve for x?

2.5 x=5.7

Answer 1

X is being multiplied by 2.5 so to undo that you have to divide both sides by 2.5 so x=5.7/2.5

Answer 2

To solve for x in equation
`2.5x=5.7` we should use Division property of equality.

Explanation:

Consider the given equation
`2.5x=5.7`

Division property of equality states when we divide both sides of an equation by same non zero number , then also both sides remain equal

Applying Division property of equality to the given equation

`2.5x=5.7`

Divide both sides by 2.5

`\Rightarrow (2.5x)/(2.5)=(5.7)/(2.5)`

We get,

`\Rightarrow x=2.28`

Thus, to solve for x in equation
`2.5x=5.7` we should use Division property of equality.
