Solve by substitution -4x-y=-2,y=-4x+3​

Mathematics
1 answer:
IRISSAK [1]3 years ago
7 0

Answer:

No solution

Step-by-step explanation:

Substitution is done by substituting one equation into another. To begin solve one equation for a variable.

Substitute y=-4x+3​ into -4x-y=-2.

-4x -(-4x + 3) = -2

-4x + 4x - 3 = -2

-3=-2

This is a false statement and there is no variable present anymore. This means the equations have no solution.
