Take the equation 103=-7(x+8)+7(x+7). Jamie says this equation has no solution. Mick says it does. Who is correct? Why?

Answer 1

`&#128075` Hello ! ☺️

Explanation:

`103 = - 7(x + 8) + 7(x + 7)`

`103 = - 7x - 56 + 7x + 49 = 0x + 7`

0x= 7 => x ∉ |R

`\boxed{\color{gold}{S = ∅}}`

Jamie is right.
