7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5

Answer:
After 140 days
Step-by-step explanation:
The next time both plants will be watered together is simply the LCM of 10 and 14.
10 has multiples: 10, 20, 30, 40 , 50 ....
14 has multiples: 14, 28, 42, 56 ....
When will they next be equal?? That's the LCM.
We first do prime factorization of the numbers and then multiply each factor the greatest number of times it occurs in either number.
<u>Prime Factorization</u>
10 = 2 * 5
14 = 2 * 7
So,
LCM = 2^2 * 5 * 7 = 140
