Question

0.4x + 0.4 = 0.6x - 0.8 what is the value of x

Answer 1

`\boxed {x = 6}`

Explanation:

Solve for the value of
`x`:

`0.4x + 0.4 = 0.6x - 0.8`

-Take
`0.6x` and subtract it from
`0.4x`:

`0.4x + 0.4 - 0.6x = 0.6x - 0.6x - 0.8`

`-0.2x + 0.4 = - 0.8`

-Subtract
`0.4` to both sides:

`-0.2x + 0.4 - 0.4 = - 0.8 - 0.4`

`-0.2x = -1.2`

-Divide both sides by
`-0.2`:

`(-0.2x)/(-0.2) = (-1.2)/(-0.2)`

-Expand by multiplying the numerator and the denominator by
`10`:

`x = (-12)/(-2)`

`\boxed {x = 6}`

So, the value of
`x` is
`6`.

Answer 2

The value of x is x=6
