Answer:
[tex]\frac{b}{9} + 3 = 7[/tex]
Step-by-step explanation:
The phrase "x more than y" indicates addition; x + y.
"Three more than the quotient of a number and 9" would mean that we would have to add 3 to the quotient of the unknown number and 9.
The "quotient of a number and 9" can be written as [tex]\frac{b}{9}[/tex] .
Finally, we would add "= 7" to the end of the equation to represent "equals 7".
"Three more than the quotient of a number and 9 equals 7" is [tex]\frac{b}{9} + 3 = 7[/tex].
Hope this helps.
