Answer:
146x-288 OR 2(73x-144)
Step-by-step explanation:
I would start by making all fractions improper. So,
8x-8/7(4/3x-12)
Now distribute.
8x-32x/21-96/7
Now multiply through by 21 to get rid of fractions.
178x-32x-96(3)
178x-32x-288
Simplify by combining like terms.
146x-288
You can leave it like this, or factor.
2(73x-144)
