Question

Which could be a step used when solving the equation 5x+10=7.5x?

Answer 1

Putting all the x's to one side.

Explanation:

By doing this, you would get:

10 = 2.5x

so,

4 = x

Answer 2

We subtract 5x from both sides

Explanation:

Step 1: Subtract 5x from both sides

`5x + 10 = 7.5x`

`10 + 5x - 5x = 7.5x - 5x`

`10 = 2.5x`

Step 2: Divide both sides by 2.5

`(10)/(2.5) = (2.5x)/(2.5)`

`4 = x`

Answer: We subtract 5x from both sides
