Complete the statements about the system of linear equation respresented by the tables the equation respented the left table is

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 =

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
