Answer:
x+4y+5=0. multiply by 5
5x+20y+25=0
Step-by-step explanation:
5x+20y=25
5x+20y=25
0
hence pair of linear equation have 0 solution. or no solution.

Answer:
Add '-5' to each side of the equation.
5 + x + -5 + 4y = 0 + -5
Reorder the terms:
5 + -5 + x + 4y = 0 + -5
Combine like terms: 5 + -5 = 0
0 + x + 4y = 0 + -5
x + 4y = 0 + -5
Combine like terms: 0 + -5 = -5
x + 4y = -5
Add '-4y' to each side of the equation.
x + 4y + -4y = -5 + -4y
Combine like terms: 4y + -4y = 0
x + 0 = -5 + -4y
x = -5 + -4y
Simplifying
x = -5 + -4y
