Solve the system of equations. {:[2x+7y=3],[x=-4y],[x=◻],[y=◻]:}

Identify Equations: Identify the given system of equations. We are given the following system of equations: 2x + 7y = 3 x = -4y We need to find the values of x and y that satisfy both equations.Substitute x: Substitute the value of x from the second equation into the first equation. Since x = -4y, we can replace x in the first equation with -4y: 2(-4y) + 7y = 3Simplify and Solve: Simplify the equation and solve for y. 2(-4y) + 7y = 3 -8y + 7y = 3 -y = 3 y = -3Substitute y for x: Substitute the value of y back into the second equation to find x. x = -4y x = -4(-3) x = 12

Identify Equations: Identify the given system of equations. $\newline$ We are given the following system of equations: $\newline$ $2x + 7y = 3$ $\newline$ $x = -4y$ $\newline$ We need to find the values of $x$ and $y$ that satisfy both equations.
Substitute $x$ : Substitute the value of $x$ from the second equation into the first equation. $\newline$ Since $x = -4y$ , we can replace $x$ in the first equation with $-4y$ : $\newline$ $2(-4y) + 7y = 3$
Simplify and Solve: Simplify the equation and solve for $y$ . $2(-4y) + 7y = 3$ $-8y + 7y = 3$ $-y = 3$ $y = -3$
Substitute $y$ for $x$ : Substitute the value of $y$ back into the second equation to find $x$ .
$x = -4y$
$x = -4(-3)$
$x = 12$
