Question

Solve the system for (y) x+5y =-4; -x+5y=-16

Answer 1

Answer:

x - 5y= -4 (equ...1)

-x + 5y=-16 (equ...2)

From equ... 1

x= -4 + 5y (equ... 3)

Substitute equ...3 into equ...2

-4 + 5y + 5y=-16

-4 + 10y=-16

Collect like terms

10y=-16 + 4

10y=-12

Divide both side by 10

y= -12/10 or -1.2

Substitute y= -1.2

x=-4 + 5y

x=-4 + 5(-1.2)

x=-4 - 6

x= -10

Hence,x= -10,y=-1.2 or-12/10
