please answer my question quickly because i have a quiz tomorrow.
You have an English language sentence that we need to translate into Mathematics language.
English) (the product of a number and 9), (increased by 4), (is 58)
Math) (Number x 9), (+ 4), (= 58)
I put in the () to show you what parts go together
Call the Number N, we can use anything (x,s, ...) but N makes sense
(N x 9) + 4 = 58
Can you do the rest? subtract 4 from both sides, divide both sides my 9, there is the answer
