To find the solution to the system of equations \( y = x - 1 \) and \( y = -2x - 4 \), we need to determine where the two lines intersect.
-
Set the equations equal to each other:
\[ x - 1 = -2x - 4 \]
-
Solve for x:
\[ x + 2x = -4 + 1 \] \[ 3x = -3 \] \[ x = -1 \]
-
Substitute \( x = -1 \) back into one of the original equations to find y. We'll use \( y = x - 1 \):
\[ y = -1 - 1 = -2 \]
Thus, the coordinates of the solution to the system of equations are:
\[ (-1, -2) \]
So, the answer is:
\[ \left(-1, -2\right) \]
