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

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
