Answer:
y = 9
Step-by-step explanation:
Exponent Rule: 
xⁿ/x³ = x⁶
xⁿ⁻³=x⁶
n = 9
Answer:
x=−1 or x=−6
Step-by-step explanation:
Multiply all terms by x and cancel:
xx+6=−7x
x2+6=−7x(Simplify both sides of the equation)
x2+6−−7x=−7x−−7x(Subtract -7x from both sides)
x2+7x+6=0
(x+1)(x+6)=0(Factor left side of equation)
x+1=0 or x+6=0(Set factors equal to 0)
x=−1 or x=−6
Check answers. (Plug them in to make sure they work.)
x=−1(Works in original equation)
x=−6(Works in original equation)
