If y(x) = 1/3x, y(-18) = 1/[3(-18)] = -1/54.
If: x = -5 Then: y = (3*-5)-1 = -16
-4
X - Y = 2 When X = 3 you have 3 - Y = 2 Moving Y to RHS: 3 = Y + 2 Moving 2 to LHS: 1 = Y
x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
x = 3 and 1/3 y = -1/3
If y(x) = 1/3x, y(-18) = 1/[3(-18)] = -1/54.
y= x-1y= 3Since y equals 3, you can replace any "y" you see with a three.3= x-1Move the one to the other side.3+1 = x -1 +14=x(you already knew y=3)
-6
If x+y = 3 and y times x = 2 then y = 1.
If: x = -5 Then: y = (3*-5)-1 = -16
-4
x equals -12 and y equals 1/4 of -12, so y = -3.
x=1, y=3 . . . √ x= -1, y= -3 . . . √ x=1, y=-3 . . . x=-1, y=3 . . .
X = 2 and Y = 3.
