hi
I need the graph to answwer your question
Answer:
I believe its the second one but i could be wrong
HHHH
Step-by-step explanation:
12 bikes
9 tricycles
x+y=21
2x+3y=51
x=-y+21
2(-y+21)+3y=51
-2y+42+3y=51
y+42=51
y=9
x=12
(3,-4)
Equation ----> 2(c - 40)
c = -40
2(c - 40)
= (2c) - (80)
= 2c - 80
= +
