Antonio is seven less than four times his daughter's age. Antonio is 45; how old is his daughter?

OpenStudy (lgbasallote):

let daughter's age = x that means antonio is 7 less than four times x so antonio is 4x - 7 does that help?

OpenStudy (anonymous):

d=daughter's age A=antonio A=45 A=4d-7 45=4d-7 52=4d 13=d
