pls give me the answer i'll give you a brainliest :)

Answer:
x = 6
y = -1
Step-by-step explanation:
We have to use substitution for the system of equations.
x = -6y
4x + 10y = 14
Because we know that [x = -6y], we can get rid of the x value by substituting y into the equation, [4x + 10y = 14].
4 x -6y + 10y = 14
Simplify.
-24y + 10y = 14
-14y = 14
Divide both sides by -14.
-14y = 14
÷-14 ÷-14
y = -1
From y, we can also find out the x value, as [x = -6y].
We now know that y = -1.
Therefore, we have to substitute again.
x = -6y
y = -1
x = -6 x -1
x = 6
Hence, x = 6 and y = -1.
Sorry it took so long to answer.
