Q. Evaluate x−(−y) x-(-y) where x=−2.31 x=-2.31 and y=5.9 y=5.9 .
  1. Identify values of xx and yy: Identify the values of xx and yy. We are given x=−2.31x = -2.31 and y=5.9y = 5.9. We need to substitute these values into the expression x−(−y)x-(-y).
  2. Substitute values into expression: Substitute the values into the expression. The expression is x−(−y)x-(-y). Substituting the given values, we get −2.31−(−5.9)-2.31 - (-5.9).
  3. Simplify the expression: Simplify the expression.\newlineThe double negative in −(−5.9)-(-5.9) becomes a positive, so the expression simplifies to −2.31+5.9-2.31 + 5.9.
  4. Perform the addition: Perform the addition.\newlineNow we add the two numbers: −2.31+5.9=3.59-2.31 + 5.9 = 3.59.
