To solve the equation: 1/4x + 2/5(104-x) = 32 First, distribute the 2/5 to the terms inside the parentheses: 1/4x + 2/5 * 104 - 2/5x = 32 Multiply 2/5 by 104: 1/4x + (2/5 * 104) - 2/5x = 32 1/4x + 208/5 - 2/5x = 32 Next, combine like terms: (1/4 - 2/5)x + 208/5 = 32 To find a common denominator for 1/4 and 2/5, we multiply the denominators together (4 * 5 = 20): (5/20 - 8/20)x + 208/5 = 32 Simplify the equation: (-3/20)x + 208/5 = 32 Multiply both sides of the equation by the common denominator (20) to eliminate the fraction: 20 * (-3/20)x + (20 * 208/5) = 20 * 32 -3x + 416 = 640 Subtract 416 from both sides: -3x = 224 Divide both sides by -3 to solve for x: x = -224/3 or x = -74.67 (rounded to two decimal places) Therefore, the solution to the equation is x = -74.67.
