Hey there again!
First , let's add 17 on each of your sides (we have to get the "X" by itself , right?
Like: -12x - 17 + 17
= -89 + 17
-89 + 17 = -72
So, divide by -12 on each of your sides since both numbers goes into 12
Like: 12x / -12 = -1
= -72 / -12 = 6
X = 6
Good luck on your assignment and enjoy your day!
