Penjelasan dengan langkah-langkah:

[tex]1. Sederhanakan:A. \((6x + 1) + 3(x - 2)\) = \(6x + 1 + 3x - 6\) = \(9x - 5\)B. \(2(-a + b) - 4(a + 3)\) = \(-2a + 2b - 4a - 12\) = \(-6a + 2b - 12\)C. \(-(a - 8) + 5(-2a + 44)\) = \(-a + 8 - 10a + 220\) = \(-11a + 8 + 220\) = \(-11a + 228\)D. \(-3(3x - 5) + -32(-22a² + 10)\) = \(-9x + 15 + 704a² - 320\) = \(704a² - 9x - 305\)[/tex]

[tex]2. Sederhanakan:A. \((50x + 23) : 2\) = \(25x + 11.5\)B. \((25y - 23) : (24/2)\) = \((25y - 23) : 12\)C. \((235y + 333) : (324/222)\) = \((235y + 333) : 1.459\)[/tex]

[tex]3. Selesaikan:A. \(4x = 32\) \(x = 32/4\) \(x = 8\)B. \(8x = 4\) \(x = 4/8\) \(x = 1/2\)C. \((1/5)x = 6\) \(x = 6 * 5\) \(x = 30\)[/tex]
