\[-3y - 7 = 8 - 16 + 2y\]
\[-3y - 7 = -8 + 2y\]
\[-3y - 2y = -8 + 7\]
\[-5y = -1\]
\[y = \frac{-1}{-5} = \frac{1}{5} = 0.2\]
Ответ: y = 0.2
\[-4 + 10x = 2x - 6 - 5\]
\[-4 + 10x = 2x - 11\]
\[10x - 2x = -11 + 4\]
\[8x = -7\]
\[x = \frac{-7}{8} = -0.875\]
Ответ: x = -0.875
\[4x - 2x - 14 = 6 - 2x\]
\[2x - 14 = 6 - 2x\]
\[2x + 2x = 6 + 14\]
\[4x = 20\]
\[x = \frac{20}{4} = 5\]
Ответ: x = 5
\[1.24x - 1.76x = 6.58 - 3.46\]
\[-0.52x = 3.12\]
\[x = \frac{3.12}{-0.52} = -6\]
Ответ: x = -6
\[-4.92y - 0.08y - 5.12 = -0.88 - y\]
\[-5y - 5.12 = -0.88 - y\]
\[-5y + y = -0.88 + 5.12\]
\[-4y = 4.24\]
\[y = \frac{4.24}{-4} = -1.06\]
Ответ: y = -1.06
\[3 - 2 = 1\]
\[\frac{1}{2} \times 100\% = 50\%\]
Ответ: 3 больше 2 на 50%
\[3 - 2 = 1\]
\[\frac{1}{3} \times 100\% = 33.33\%\]
Ответ: 2 меньше 3 на 33.33%
