Add 7t to both sides: Start by adding 7t to both sides of the equation to move all the t terms to one side.−7t−8+7t=10+2t+7tThis simplifies to:−8=10+9t
Subtract 10 from both sides: Next, subtract 10 from both sides to isolate the term with t on one side.−8−10=10+9t−10This simplifies to:−18=9t
Divide both sides by 9: Finally, divide both sides by 9 to solve for t.−918=99tThis simplifies to:t=−2
