Q. if n+57=95n + 57 = 95 and n+32−z=43n + 32 - z = 43 then what is zz?
  1. Solve for nn: First, solve the equation n+57=95n + 57 = 95 to find the value of nn.
    n+57=95n + 57 = 95
    Subtract 5757 from both sides to isolate nn.
    n=95−57n = 95 - 57
    n=38n = 38
  2. Substitute nn into second equation: Now, substitute the value of nn into the second equation n+32−z=43n + 32 - z = 43.38+32−z=4338 + 32 - z = 43Combine the like terms (38+32)(38 + 32) to simplify the equation.70−z=4370 - z = 43
  3. Find value of z: To find the value of z, subtract 7070 from both sides of the equation.\newline- z=43−70z = 43 - 70\newline- z=−27z = -27
  4. Solve for zz: Since we have −z-z, we need to multiply both sides by −1-1 to solve for zz.\newlinez=−27×−1z = -27 \times -1\newlinez=27z = 27
