Чтобы решить линейные уравнения, поступим следующим образом: 1) \(10x - 8 = 0\) \[ 10x = 8 \] \[ x = \frac{8}{10} = 0.8 \] 2) \(4x - 7 = 0\) \[ 4x = 7 \] \[ x = \frac{7}{4} = 1.75 \] 3) \(8x - 5 = 10x\) \[ 8x - 10x = 5 \] \[ -2x = 5 \] \[ x = \frac{-5}{2} = -2.5 \] 4) \(6x = x - 2\) \[ 6x - x = -2 \] \[ 5x = -2 \] \[ x = \frac{-2}{5} = -0.4 \] 5) \(9x - 4 = 10x\) \[ 9x - 10x = 4 \] \[ -x = 4 \] \[ x = -4 \] 6) \(9 = 5(x + 9)\) Раскрываем скобки: \[ 9 = 5x + 45 \] \[ 5x = 9 - 45 \] \[ 5x = -36 \] \[ x = \frac{-36}{5} = -7.2 \] 7) \(-3x + 9 = 0\) \[ -3x = -9 \] \[ x = \frac{-9}{-3} = 3 \] 8) \(-5x + 6 = 0\) \[ -5x = -6 \] \[ x = \frac{-6}{-5} = 1.2 \] 9) \(5x - 3 = -10x\) \[ 5x + 10x = 3 \] \[ 15x = 3 \] \[ x = \frac{3}{15} = \frac{1}{5} = 0.2 \] 10) \(x + 9 = -9x\) \[ x + 9x = -9 \] \[ 10x = -9 \] \[ x = \frac{-9}{10} = -0.9 \] 11) \(3x - 8 = -x\) \[ 3x + x = 8 \] \[ 4x = 8 \] \[ x = \frac{8}{4} = 2 \] 12) \(-7 = 5(x + 5)\) Раскрываем скобки: \[ -7 = 5x + 25 \] \[ 5x = -7 - 25 \] \[ 5x = -32 \] \[ x = \frac{-32}{5} = -6.4 \] Таким образом, у нас есть решения для всех уравнений.
