10,72+0,324:(5,5-t:78)=10,8

To solve this equation, we need to follow the order of operations (PEMDAS) and simplify step by step.

First, let's calculate the division: 0,324 / (5,5 - t:78) = 10,8

Next, let's simplify the expression within the parentheses: 5,5 - t:78 = 0.324 / 10.8

To find the value of t, we need to isolate the variable. Therefore, let's rearrange the equation: t:78 = 0.324 / 10.8 - 5.5

Next, simplify the right side of the equation: t:78 = 0.03 - 5.5

Now, let's subtract the two values: t:78 = -5.47

Finally, to solve for t, we need to multiply both sides of the equation by 78: t = -5.47 * 78

Therefore, the value of t is -426.66.
