To solve for x, you need to do inverse operations to both sides. (also, you need to make 2 possibilities for the absolute value)
8 |x+7-3| = 5
Divide both sides by 8 and simplify like terms:
|x+4| = 5/8
Then, you need to separate into 2 different equations like this:
x +4 = 5/8 and
x + 4 = -5/8
Then, solving for x like this:
x = 5/8-4
x = -5/8-4
Which gets you
x = -3.375 and
x = -4.625
Hope this helped!
By the way, I'm getting closer to leveling up, so if you liked my answer, you could reward me with brainliest answer. That'd be great!
