Answer:7t+5
Explanation:
Circle the 2 variables (T)
Next re-write the equation and put the varbiles equation 6t+t.
Then you have 7-2 left, you then put it next to the new equation but make sure when you do that it looks like this 6t+t+7-2.
Last you solve and your answer should be 7t+5.
Note: If a variable is alone like the t then make sure you put a one next to it
