Answer:
5
Step-by-step explanation:
If <em>e = 7,</em> you would replace e in the expression <em>e - 2 </em>with 7 so that the expression becomes <em>7 - 2</em> which results in 5.
Does that help?
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
