Which ordered pair is a solution of the system of equations?

y = 3x + 1
y = 5x - 1

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 =

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles
