Answer:
Explanation:
To solve the system of equations:
1. Start with the given equations:
2r + 7y = 3
r = -4y
2. Substitute the value of r from the second equation into the first equation:
2(-4y) + 7y = 3
-8y + 7y = 3
-y = 3
3. Divide both sides of the equation by -1 to isolate y:
y = -3
4. Substitute the value of y back into the second equation to find the value of r:
r = -4(-3)
r = 12
So, the solution to the system of equations is:
R = 12
Y = -3
Please note that the values of r and y obtained from the solution satisfy both equations of the system.
