Answer:
12
Step-by-step explanation:
first u have to move 7/-10 to the other side and divide while the x is on the same side. to divide u have to flip over 7/10 so it would look like this x = 42/5 x 10/7 ( there are 2 negative signs so the answer would become positive ) ok so 7 and 42 cross of leaving 6 in the numerator and 5 and 10 would cross off leaving 2 in the numerator now if you multiply 6 and 2 you will get the answer of 12
