Full solution

Q. Is t=11 t = 11 a solution to this equation?\newline9=t7 9 = t - 7 \newlineChoices:\newline(A)yes\newline(B)no
  1. Substitute value into equation: We are given t=11t = 11. Let's substitute the value of tt into the equation 9=t79 = t - 7.\newline9=1179 = 11 - 7
  2. Calculate subtraction: Calculate what is 1111 minus 77.\newline117=411 - 7 = 4
  3. Compare results: Compare the result of the calculation with the left side of the equation. \newline9=49 = 4\newlineThis is not true, so t=11t = 11 is not a solution to the equation 9=t79 = t - 7.
