Question

Solve the system by graphing
Y=-x-4
Y=3/5x+4

Answer 1

x-y=4, 3x-5y=-4

Explanation:

step (1)

write the equation in the form ax+by=c

step (2)

put the equations below each other

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

3x-5y=-4....(2)

Multiply (1) by (-5) then add (1) and (2)

-5x+5y=-20

3x-5y=-4

-2x=-24 then x=12 from (1) y=8
