Answer

$T=299\ K$

Work Step by Step

For this calculation, digits that are not significant numbers will be underlined, and the numbers will have up to 4 decimal places to avoid rounding off errors: $102\underline{0.896}(T-296.0)+39.7\underline{365}(T-369.0)=0$ $(102\underline{0.896}+39.7\underline{365}).T=302\underline{185.216} + 146\underline{62.7685}$ $106\underline{0.6325}\times T = 316\underline{847.9845}$ $T = 298.\underline{7349}$ So, rounding the final result: $T=299\ K$
