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
To find the mean add all the numbers up then divide by how many numbers you have.
-36+(-25)+12+(-4)+18= (-35)
there are a total of five numbers so divide by 5
(-35)/5=(-7)
answer -7
