Five years ago..Aprils age was half of the age she will be in 8 years..How old is he now..Please explain as well..Thanks

18

Step-by-step explanation:

let a be April's current age

a - 5 = (a + 8)

a - 5 = 0.5a + 4

a - 0.5a = 4 + 5

0.5a = 9

a = 18

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
