Answer:
A. No solutions
Step-by-step explanation:
2x-2x=-9
0= -9
Since 0 does not equal -9, there are no solutions.
The answer is 7, your welcome :).
Answer:
13-13x
Step-by-step explanation:
3*2=6
(6-5x+6) + (9-8x-8)
Combine Like Terms
(12-5x) + (1-8x)
Put x on one side and numbers on the other.
(12+1) + (-5x+ (-8x))
13-13x

The greatest factor of 60 and 75 is 15.
Reasoning: I found the factors and prime factorization of 60 and 75. The biggest common factor number is the GCF number. So the greatest common factor 60 and 75 is 15.
