Question

9 decreased by x and y

Answer 1

9-(x+y)

Explanation:

9 would be before x and y for the equation bc it states 9 first

when it says x and y, it means that you add so x+y but you have to put in parentheses bc you have to find the value of x and y first

so lets say, for example, 9 decreased by x and y, x=3 and y=2

so the equation is 9-(x+y)

so then the new equation would be 9-(3+2)

so then 3+2 is 5 so you subtract 5 from 9 which would be 4

hope this helps

Answer 2

9 - (x + y)

i could tell you more but i dont know the value of x and y
