Answer:
x = -16.
Step-by-step explanation:
x/-4 - (-8) = 12
x/-4 + 8 = 12
x/-4 = 12 - 8
x/-4 = 4
Cross multiply:
x = -4 * 4
x = -16.
It is 2 12/20 simplified is 2 6/10 simplified is 2 3/5
So if you want it simplified it is 2 6/10 but if you just want the answer I think it would be 2 3/5
Hope this is helpful
And have a great day
