Question

Solve the system of linear equations.

y=x+3
-4x+4y=28

Answer 1

you did it wrong

Answer 2

To solve this system of linear equations, we can solve for one variable in the first equation and substitute it into the second equation.

From the first equation, we have y = x + 3.

Substituting this into the second equation:

-4x + 4(x + 3) = 28

-4x + 4x + 12 = 28

12 = 28

This equation is not possible because 12 is not equal to 28.

Therefore, there is no solution to this system of linear equations.

Answer 3

Apologies for the mistake. Let's solve the system of equations correctly.

The given equations are:
1) y = x + 3
2) -4x + 4y = 28

From equation 1, we can substitute the value of y in equation 2:
-4x + 4(x + 3) = 28

Expanding the brackets:
-4x + 4x + 12 = 28

Combine like terms:
12 = 28

This equation is not possible since 12 is not equal to 28.

Therefore, the system of equations is inconsistent and does not have a solution.
