Answer:
t = 2
Explanation:
To solve this equation, add nine to both sides. This will isolate the variable (t) and allow us to find its value.
[tex]-9 + t = -7\\(-9 + 9) + t = (-7 + 9)\\t = (-7 + 9)\\t = 2[/tex]
If you would like to double check that the variable (t) does in fact equal two, substitute the value of the variable in the equation and solve.
[tex]-9 + t = -7\\-9 + 2 = -7\\-7 = -7 [true][/tex]
Therefore, the value of t in the given equation is 2.
