Add x to both sides of the equation: 5/7 - x + x = 3/11 + xSubtract 3/11 from both sides of the equation: 5/7 - 3/11 = 3/11 - 3/11 + xx = 5/7 - 3/11Find the least common multiple of 7 and 11, which is 77.Multiply both the numerator and the denominator of each fraction by the same number to get the number 77 in the denominator 5/7 = 55/77 and 3/11 = 21/77.Find x: x = 55/77 - 21/77 = 34/77. So 34/77 is the answer.
