Answer:
(x, y) = (77/240, -3/10)
Step-by-step explanation:
It is convenient to write the equations in standard form.
Multiplying the first equation by 21 gives ...
21y = 24x -14
Multiplying the second equation by 8 gives ...
24x +9y = 5
Then the system of equations in standard form is ...
Subtracting the first from the second, we get ...
(24x +9y) -(24x -21y) = (5) -(14)
30y = -9
y = -9/30 = -3/10
Substituting this into the second equation, we have ...
24x +9(-3/10) = 5
24x = 7.7 . . . . . . . add 27/10
x = 7.7/24 = 77/240
The solution is (x, y) = (77/240, -3/10).
Are you solving for x or y?
Answer: 17
Step-by-step explanation:
If there are 5 cows and they add 12 then there are 17 cows in total
12+5=17
The answer is that there is a proximity 10 miles of coast 9.904... it be exact
The first one is D. Y=-3+8x
The second one is G. -3/2x=y+2
