Answer:
=- , =
Step-by-step explanation:
3-4=2
3=2+4
3=6 (divide both sides by 3)
=2 (simplify)
x=±
Y= 4-2x
-2... y= 4- 2 (-2) = 4 - -4=4+4= 8
-1... y= 4 - 2(-1) = 4 - -2=4+2= 6
1... y= 4 - 2 (1) = 4 - 2 = 2
3... y = 4 - 2(3) = 4 - 6 = -2
4... y = 4 - 2(4) = 4 - 8 = -4
{8, 6, 2, -2, -4}
{-4, -2, 2, 6, 8}
