Suppose you are solving the system of equations below using the substitution method. What would the second equation look like after you substitute "9-x"?

41/2 - 1 1/3 what is the answer as a fraction?

Which function has the same domain as y=2x

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 =
