The sum of twice a number and 4 is equal to the sum and 5

Which expression is equivalent to? assume x > 0 and y > 0.

If eh = hg and hg=16, find the diameter of k

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 =
