Find the value of t for which the equation t + 3 = 5 is satisfied.

The solution of an equation is the value of the variable in an equation that satisfies the equation.

 Given, t + 3 = 5

To check which of the following value is the solution to the given equation, we can use the trial and error method.

Put t = 2, 2 + 3  = 5 = 5, so 2 is the solution.

Put t = 3, 3 + 3  = 6 $\ne$ 5, so 3 is not the solution.

Put t = 4, 4 + 3  = 7 $\ne$ 5, so 4 is not the solution.

Put t = 7, 7 + 3  = 10 $\ne$ 5, so 7 is not the solution.

Hence, t = 2 is the solution.
