Answer :
Answer:
-26/25
Step-by-step explanation:
-9/25 + x = -21/15
Let's reduce the numerator (number before "/") and denominator (number after "/") of the second fraction by 3.
So we get
-9/25 + x = -7/5
x = 9/25 - 7/5
Let's bring the fractions to a common denominator, it will be 25.
For that we have to multiply the numerator and denominator of the second fraction by 5.
x = 9/25 - 35/25
Now the numerator will be the differences of first and second fraction and the denomiator will be 25.
x = (9-35)/25
x = -26/25
