X represents elga’s age
x+14+x=98
combine like terms
2x+14=98
subtract 14 from both sides
2x=84
divide both sides by 2 to isolate the variable (x)
x=42
elga is 42 years old.
if alvin is 14 years older than elga, and elga is 42, then alvin is 56 years old. 42+56=98

In 36 days will the science and math teachers both give tests on the same day again.

Step-by-step explanation:

Here we have , The 6th grade science teacher gives a test every 12 days and the math teacher gives a test every 9 days. Today, both the science and math are giving tests. We need to find In how many days will the science and math teachers both give tests on the same day again . Let's find out:

It's given that science teacher gives a test every 12 days and the math teacher gives a test every 9 days . In order to find the number of days after which they'll give test at same day , we will find LCM of 12 & 9 . i.e.

⇒ $12(1)=12\\12(2)=24\\12(3)=36$ and ,
