Bernard solved the equation 5 x + (negative 4) = 6 x + 4 using algebra tiles. Which explains why Bernard added 5 negative x-tiles to both sides in the first step of the solution? He wanted to create zero pairs on the left side of the equation to get a positive coefficient of x on the right side. He wanted to combine more negative tiles with the 4 negative tiles on the left side of the equation. He wanted to remove the larger coefficient on the left side of the equation. He wanted to have 10 x-tiles on the left side of the equation.
