Question

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

$👋$ Hello ! ☺️

Step-by-step 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.

* Any number multiplied by 0 gives 0.
