Full solution

Q. Rewrite in simplest terms: 0.9y0.7(9y1) 0.9 y-0.7(-9 y-1) \newlineAnswer:
  1. Distribute 0.7-0.7: Distribute the 0.7-0.7 across the parentheses.\newline0.9y0.7(9y1)=0.9y(0.7×9y)(0.7×1)0.9y - 0.7(-9y - 1) = 0.9y - (-0.7 \times -9y) - (-0.7 \times -1)
  2. Multiply by terms: Multiply 0.7-0.7 by each term inside the parentheses.\newline0.9y(0.7×9y)(0.7×1)=0.9y6.3y+0.70.9y - (-0.7 \times -9y) - (-0.7 \times -1) = 0.9y - 6.3y + 0.7
  3. Combine like terms: Combine like terms.\newline0.9y6.3y+0.7=(0.9y6.3y)+0.7=5.4y+0.70.9y - 6.3y + 0.7 = (0.9y - 6.3y) + 0.7 = -5.4y + 0.7
