Full solution

Q. If −26+z=15 -26+z=15 , what is the value of z z ?
  1. Isolate the variable z: Isolate the variable z on one side of the equation.\newlineTo isolate z, we need to add 2626 to both sides of the equation to cancel out the −26-26 on the left side.\newline−26-26 + z + 2626 = 1515 + 2626
  2. Perform the addition: Perform the addition on both sides of the equation.\newlinez = 15+2615 + 26\newlinez = 4141
  3. Check the solution: Check the solution by substituting the value of zz back into the original equation.\newline−26+41-26 + 41 should equal 1515.\newline−26+41=15-26 + 41 = 15\newline15=1515 = 15\newlineThe left side equals the right side, so our solution is correct.
