A system of linear equations is given below.
{2x+8y=28
2x+8y=29

How many solutions does this system have?
A. 2
B. infinitely many
C. 1
D. 0

Respuesta :

I believe it’s a because it sounds right
Answer: D


Explanation:


Solve using substitution:

{ 2x+8y=28
2x+8y=29

Since both left sides are 2x+8y, you can set the right sides equal to each other:

28=29

This statement is false because 28 will never equal 29. This means that there is no solution (the lines never intersect).
