Question

How do you solve `7.5x – 3.2 = 12.5x`?

Answer 1

`-0.64`

Explanation:

You have `7.5x-3.2=12.5x`.

Step I (Subtract 7.5x form both sides)
`7.5x-3.2-7.5x=12.5x-7.5x`

Step II (`7.5x-7.5x=0; 12.5x-7.5x=5x`)
`-3.2=5x`

Step III (Divide both sides by 5)
`-3.2/5=(5x)/5`

Step IV (`-3.2/5=-0.64`)

ANSWER IS `x=-0.64`
