Answer:

x + 3 = 9 (original equation )

x = 9 – 3 (take the constant term to the other side so that the variable x is isolated.)

x = 6

So x = 6 is the required solution to the equation.

Answer:

x-5

Step-by-step explanation:

Consider the expression

\dfrac{3x^3-15x^2+15x-75}{3x^2+15}

Its numerator 3x^3-15x^2+15x-75 is equivalent to

3x^3-15x^2+15x-75\\ \\=3x^2(x-5)+15(x-5)\\ \\=(x-5)(3x^2+15)

Therefore, given expression can be rewritten as

\dfrac{(x-5)(3x^2+15)}{3x^2+15}=x-5

Note that 3x^2+15\neq 0, so we can divide the numerator and the denominator by non-zero expression 3x^2+15.
