I presume “to simplify” means to make them into a single fraction. The approach is very similar to how you would convert mixed fractions to improper fractions.

1 + 4(3x - 1)/9
= 1 + (12x - 4)/9
= 1 + (12x/9 - 4/9)
= 1 + 4x/3 + 4/9
= 1 - 4/9 + 4x/3
= 5/9 + 1⅓ x
Since this is E Math we leave it in mixed number
