please help me with chemistry im freaking out

Solution (partial):

$\text {The equation for combined gas laws: }\\ \dfrac{P_1V_1}{T_1} = \dfrac{P_2V_2}{T_2}\\ \text { }\\ \text {The solution requires simple algebraic operations for this setup: }\\ \text { }\\ \dfrac{1.00 atm*2.00 L}{T_1} = \dfrac{0.82atm*2.00L}{10 C} \quad | \quad \text {solve for } T_1\\ \text { }\\ \text {Algebra 1 & 2 is prerequisite for chemistry; you should already have these skills. }\\ \text { }\\ \text {Post your (attempted) solution below. Someone will check it for you. }\\ $
