Answer:
For 13: 13/30
Step-by-step explanation:
First simplify!
9x - 25 + 21x - 35 + 12 = 0
then simplify some more
9x + 21x = 30x
(-25) + (-35) + 21 + 12 = -13
30x - 13 = 0
now add 13 to both sides, 13 and -13 cancel each other out and it becomes
30x = 13
then you divide by 30 to get x by itself. 30 cancels itself out and you are left with 13/30 which doesn't simplify so that shod be your answer! I couldn't figure out 14 but I hope this helps!!!
