Question

What is the solution of the system
of equations?
2x + 5y = 20
Y=-2/5x-1

Answer 1

no solutions

Explanation:

Substitute -2/5(x) - 1 for y in 2x + 5y = 20

• 
  `2x + 5(-(2)/(5)-1)=20`
• 
  `2x + (5)((-2)/(5)x)+(5)(-1)=20` (Distribute)
• 
  `2x -2x - 5 = 20` (Simplify)
• 
  `-5 = 20` (Simplify)
• 
  `-5+5=20+5` (Add 5 to both sides)
• 
  `0 = 25`

Therefore, the answer is no solutions.
