Question

Which of the following equations could be the result of using the comparison method to solve the system shown?

x - 4y - 1 = 0

x + 5y - 4 = 0

4y+ 1 = 4 - 5y
-4y+ 1 = 4 - 5y
4y+ 1 = 5y- 4

Answer 1

-x+4y+1=0
x+5y-4=0
_______
9y-3=0
y=3/9
______
x+5(3/9)-4=0
x+15/9-4=0
x-2.3=0
x=2.3
________
2.3+5(3/9)-4=0

Answer 2

4y+ 1 = 5y- 4 is it true
