Answer:
3x=38
Step-by-step explanation:
Given that,
Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45.
Let Annie's age is x.
Emily's age = 7+2x
ATQ,
The sum of their ages is 45.
x+7+2x = 45
Taking like terms together,
x+2x = 45-7
3x=38
Hence, this is the relation between their ages.
