Question

-1/2x+2=-x+7 i need to know

Answer 1

`= ( - 1)/( \: \: 2) x + 2 = x + 7`

`= ( - 1)/( \: \: \: 2) x + 2 - x = 7`

`= ( - 3)/( \: \: \: 2)x + 2 = 7`

`= ( - 3)/( \: \ \: 2)x = 7 - 2`

`= ( - 3)/( \: \: \: 2) x = 5`

`x = 5 \: / ( - 3)/( \: \: \: 2)`

`x = 5 * ( \: \: \: 2)/( - 3)`

`x = ( - 10)/( \: \: \: 3)`

`∴ ( - 1)/( \: \: \: 2) * ( - 10)/( \: \: \: 3) = ( - 10)/( \: \: \: 3) + 7</p><p></p><p>`
