Hello!
let's make the following solution:
[tex]- (14w + 8) + 8 = 3[/tex]
we eliminate the parentheses and change the signs
[tex]- 14w - 8 + 8 = 3[/tex]
we eliminate the opposite numbers
[tex]- 14w - \diagup\!\!\!\!8 + \diagup\!\!\!\!8 = 3[/tex]
so:
[tex]- 14w = 3\;\:(simplify\:by\:-1)[/tex]
[tex]14w = -3[/tex]
[tex]\boxed{\boxed{w = -\frac{3}{14}}}\end{array}}\qquad\checkmark[/tex]
ps: the answer is correct, the question was poorly worked out with the wrong feedback.
