Y=3x-10 and 3x+2y=16
y=3x-10
subsitute 3x-10 for y in other equation
3x+2y=16
3x+2(3x-10)=16
distribute
3x+6x-20=16
9x-20=16
add 20 both sides
9x=36
divide both sides by 9
x=4
sub back
y=3x-10
y=3(4)-10
y=12-10
y=2
x=4
y=2
(4,2) is soluiton
The answer is a. here’s a picture that hopefully helps explain the reasoning/work
Answer:
49 people
Step-by-step explanation:
Take the amount of candy and divide by the amount in a serving
