The system of equations has no solution
Step-by-step explanation:
The method of substitution consists in solving one equation for a variable and replacing it in the other equation.
In this case one of the equations is already solved for one of the variables (
):
![y = -2x + 1](/tpl/images/0294/8495/1f0e4.png)
So the next step is to plug this in the other equation wich is:
![4x + 2y = -3](/tpl/images/0294/8495/ef46c.png)
So we will have
![4x + 2(-2x + 1) = -3](/tpl/images/0294/8495/16b00.png)
solving the parenthesis:
![4x-4x -2= -3](/tpl/images/0294/8495/5b70d.png)
![-2= -3](/tpl/images/0294/8495/fe1c0.png)
wich is not a valid answer, so the system of equations has no solution.
