Question

6,6+6+(−0,42t)=7+6,6−2,42t​

Answer 1

Ответ:

t = 0,5

Пошаговое объяснение:

6,6 + 6 + (- 0,42t) = 7 + 6,6 - 2,42t

Переносим всё числа c t в одну сторону а все остальные числа в другую (с изменением знака):

6,6 + 6 - 7 - 6,6 = 0,42t - 2,42

6,6 сокращается:

-1 = -2t

Домножаем на -1:

2t = 1

t = 0,5

Answer 2

To solve the equation, we'll first simplify both sides and then isolate the variable.

Let's simplify the equation step by step:

6 + 6 + (-0.42t) = 7 + 6.6 - 2.42t

Combine the like terms on each side:

12 - 0.42t = 13.6 - 2.42t

Now, let's isolate the variable 't' by moving the terms involving 't' to one side of the equation and the constant terms to the other side.

To do this, we'll start by adding 2.42t to both sides:

12 - 0.42t + 2.42t = 13.6 - 2.42t + 2.42t

Simplifying further:

12 + 2t = 13.6

Next, subtract 12 from both sides:

12 + 2t - 12 = 13.6 - 12

Simplifying further:

2t = 1.6

Finally, divide both sides by 2 to solve for 't':

(2t)/2 = 1.6/2

Simplifying further:

t = 0.8

Therefore, the solution to the equation 6 + 6 + (-0.42t) = 7 + 6.6 - 2.42t is t = 0.8.
