Let's Apply A. Determine if the given expression is a linear equation in one variable or Not.
__________1. y + 3 = 10
_________2. 3 - 4x = 1/4
_________3. ^(3) - 4 = x
_________4. x ( x + 7 ) = -3
_________5. -x + 5y = 25
_________6. 9x + 8 = -5× - 2
_________7. a - 4 = 0
_________8. ( b + 3 ) ( b - 4 ) = 12
_________9. x/9 = -1
_________10. y - 12 = 6y + 4
