Solve the system of equations using substitution.

y = −2x + 1
4x + 2y = −3

infinitely many solutions
no solution
(0, −5)
(−5, 0)

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 ():

So the next step is to plug this in the other equation wich is:

So we will have

solving the parenthesis:

wich is not a valid answer, so the system of equations has no solution.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
