Q. Is t=11 a solution to this equation?9=t−7Choices:(A)yes(B)no
Substitute value into equation: We are given t=11. Let's substitute the value of t into the equation 9=t−7.9=11−7
Calculate subtraction: Calculate what is 11 minus 7.11−7=4
Compare results: Compare the result of the calculation with the left side of the equation. 9=4This is not true, so t=11 is not a solution to the equation 9=t−7.
