Mikayla is thinking of a number. She says that the sum of a number and 5, multiplied by 3/4, is equal to 12. What are 2 equations that can be used to find Mikayla's number? A) 3/4x + 3 3/4 = 12
B) 3/4x + 5 = 12
C) 3/4 + 5 = 12
D) 3/4 (x + 5) = 12

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 =
