X^5 + x^3 + x = -3
how i can to decide it?

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
