Question

Your friend was solving the equation shown and was confused by the result "-20 = -20." Explain what this result

means.
4(y - 5) - 2y = 6y - 20 - 4y
4y - 20 - 2y = 6y - 20 - 4y
2y - 20 = 2y - 20
-20 = -20

Answer 1

It has no solutions (Option A)

Explanation:

Let me solve

`\\ \sf\longmapsto 4(y-5)-2y=6y-20-4y`

`\\ \sf\longmapsto 4y-20-2y=2y-20`

`\\ \sf\longmapsto 2y-20=2y-20`

`\\ \sf\longmapsto -20=-20`
