Answer:
the probability is 1/6, or 16.6%
For the first one your answer would be
The problem would stay the same because you can't combine like terms.
For the second one your answer would be
-8y-5x=13
12+20•3-3x-15
multiply the numbers : 20•3 = 60
12+60-3x-15
group like terms
-3x+12+60-15
add and subtract the numbers : 12+60-15=57
final answer = -3x+57
