To solve this system of equations, we can set the two equations equal to each other and solve for x:
-2x + 5 = x - 4
-2x - x = -4 - 5
-3x = -9
x = 3
Now that we have found the value of x, we can substitute it back into either of the original equations to solve for y. Let's use the second equation:
y = 3 - 4
y = -1
Therefore, the solution to the system of equations is x = 3 and y = -1.
-2x + 5 = x - 4
-2x - x = -4 - 5
-3x = -9
x = 3
Now that we have found the value of x, we can substitute it back into either of the original equations to solve for y. Let's use the second equation:
y = 3 - 4
y = -1
Therefore, the solution to the system of equations is x = 3 and y = -1.
