2) -7 i think
Step-by-step explanation:
If you are solving for a: it equals 3
distribute: 5a + 5=2a +14
get rid of extra number on one side: 5a=2a +9 (subtract 5 from both sides)
get rid of the other variable: 3a=9 (subtract 2a from both sides)
divide to isolate a: 3a/3=9/3 (divide by three on both sides)
answer= a=3
The answer for the first (3’12

Add the numbers together to finish the mixed number and add it back into the expression.
- 5
Now use the same process I showed above to convert the second mixed number to an improper fraction.
Now subtract the two fractions to find your final answer.
This means that your answer is going to be
or 3
