You would simply add the last two equations together. If v=2x+1 and t=4x-1, you can add them up. This would make 2x+1+4x-1. If you combine like terms, 1 and -1 cancel out and you are left with 6x. This means x can be anything.
Answer:
C, 12
Step-by-step explanation:
least common multiple of 4 and 6 is:
prime factorization of 4: 2*2
prime factorization of 6: 3*2
common factors: 2, so you should only multiply one of the common 2s when multiplying the factors to get the least common multiple
2*2*3=12
12 is a common denominator of 1/4 and 5/6
