Answer:
11 and 18
Step-by-step explanation:
if the smaller number is a
the larger number is a+7
their sum a + (a+7) = 29
2a + 7 = 29
2a = 29-7
2a = 22
a = 22/2
a = 11
the smaller number is 11
the larger number is 11 + 7 = 18
Answer:
x=3
Step-by-step explanation:
The approach is not very different from regular fractions.
You have to get to a common denominator to be able to add them.

7x + 9 = 30
7x = 30 - 9
x = 3
