y = -3x + 18
3x + 4y =0
Solve this the same way that Damon and I showed you.

thank you already did
(8,-6)
Yep.
thank you, I can say more then thank you.
You're welcome.
To solve the given system of equations:
1. Solve the first equation (y = -3x + 18) for y in terms of x.
We can rewrite the equation as y = -3x + 18.
2. Substitute this value of y into the second equation (3x + 4y = 0).
Replace y with (-3x + 18) in the second equation: 3x + 4(-3x + 18) = 0.
3. Simplify and solve for x.
Distribute 4 over (-3x + 18): 3x - 12x + 72 = 0.
Combine like terms: -9x + 72 = 0.
Move 72 to the other side: -9x = -72.
Divide both sides by -9: x = 8.
4. Substitute the value of x back into y = -3x + 18 to find y.
y = -3(8) + 18 = -24 + 18 = -6.
Therefore, the solution to the system of equations is x = 8 and y = -6.
