Answer
x=-2 and y=-3
Step-by-step explanation:
Step: Solvey=5x+7for y:
Step: Substitute5x+7 for y in 3x+y=−9:
3x+y=−9
3x+5x+7=−9
8x+7=−9(Simplify both sides of the equation)
8x+7+−7=−9+−7(Add -7 to both sides)
8x=−16
8x/8=−16/8
(Divide both sides by 8)
x=−2
Step: Substitute−2 for x in y=5x+7:
y=5x+7
y=(5)(−2)+7
y=−3(Simplify both sides of the equation)

Conclusion: young people like condiments.
First, let's convert things into percentages, since the number in each age category is different. There are 143 in "Under 18", 233 in "18 to 40", 161 in "40 to 60", and 122 in "over 60".
Of the under 18s: 71 of 143 = 49.7% order three or more.
Of the 18-40s: 87 of 233 = 37.3% order three or more.
Of the 40-60s: 47 of 161 = 29.2% order three or more.
Of the 60 and ups: 28 of 122 = 23.0% order three or more.
The older you are, the less likely you are to order lots of condiments.
