B. Explain each step, excluding those that are labeled as "no justification needed.” For each step, identify the property of the real numbers being used and explain how that property is being applied. 62+9x+(-8)(8+x) (no justification needed) =62+9x+(-64+(8x)) =62+9x+((-8x)+(-64)) =62+(9x+(-8x))+(-64) =62+(9+(-8))x+(-64) =62+1x-64 (no justification needed) =62+x-64 =x+62-64 =x-2 (no justification needed)
