Solve by Graphing x+y=-9 4x+y=-19

$x + y = - 9$ $4 x + y = - 19$

Step 1

Subtract $x$ from both sides of the equation.

$y = - 9 - x$

$4 x + y = - 19$

Step 2

Subtract $4 x$ from both sides of the equation.

$y = - 19 - 4 x$

$y = - 9 - x$

Step 3

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.

$(- \frac{10}{3}, - \frac{17}{3})$
