[2(x+10)] (3x-30) what is the value of x

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

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 =
