Answer:
no solutions
Step-by-step explanation:
Substitute -2/5(x) - 1 for y in 2x + 5y = 20
- [tex]2x + 5(-\frac{2}{5}-1)=20[/tex]
- [tex]2x + (5)(\frac{-2}{5}x)+(5)(-1)=20[/tex] (Distribute)
- [tex]2x -2x - 5 = 20[/tex] (Simplify)
- [tex]-5 = 20[/tex] (Simplify)
- [tex]-5+5=20+5[/tex] (Add 5 to both sides)
- [tex]0 = 25[/tex]
Therefore, the answer is no solutions.
