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.

He wanted to create zero pairs on the left side of the equation to get a positive coefficient of x on the right side. Adding 5 negative x-tiles cancels the 5 positive x-tiles on the left, leaving 1x on the right (6x − 5x = x).
