Full solution

Q. Is z=7z = 7 a solution to this equation?\newline1=z61 = z - 6\newlineChoices:\newline(A)yes\newline(B)no
  1. Substitute zz into equation: We are given z=7z = 7. Let's substitute the value of zz into the equation 1=z61 = z - 6.\newline1=761 = 7 - 6
  2. Perform subtraction: Now, let's perform the subtraction on the right side of the equation. 1=11 = 1
  3. Compare both sides: After the substitution and calculation, we compare both sides of the equation. Since both sides are equal, z=7z = 7 is indeed a solution to the equation 1=z61 = z - 6.
