The graph is proportional
3 times 2 is 6 then you do 6 times 3 which is 18 +3 =21 you add them all up 21+6=27
14r + 16 = 100
isolate the r: first subtract 16 from both sides
14r + 16 (-16) = 100 (-16)
how it looks now:
14r = 84
Than divide 14 from both sides to isolate the r
14r/14 = 84/14
how it looks now:
r = 6
Answer: r = 6

Y=5x-7 -3x-2y=-12 (2,3)
y=4x+3 y=-x-2 (-1,-1)
12x+8y=140 5 adults 10 children
12(5)+8(10)=140
60+80=140
