Coincident lines are lines that are the same.
In the beginning of both equations we have '4x' and '8x'.
Note that 8 / 4 = 2.
Multiply the rest of the numbers in the first equation by 2.
5y * 2 = 10y
8 * 2 = 16
So our 2nd line will be:
8x + 10y = 16
Answer:
x = 12, y = 0
Step-by-step explanation:
Use elimination.
24y = 0
y = 0
Then plug back into the second equation.
2x + 9(0) = 24
2x = 24
x = 12
Plug back into the first equation to check.
Answer:
72
Step-by-step explanation:
only 35 from A and 37 from B fit the range, so 35+37 is 72
