Question

−3,69n+14+8,7=(−18+8,7)−5,69n .−3,69n+14+8,7=(−18+8,7)−5,69n .

Answer 1

Объяснение:

−3,69n+14+8,7=(−18+8,7)−5,69n

-3,69n+14+8,7=-9,3-5,69n

-3,69n+5,69n=-9,3-14-8,7

-2n=-23,3-8,7

-2n=-32

n= 16

Answer 2

Let's solve the equation step by step:

Starting equation: -3.69n + 14 + 8.7 = (-18 + 8.7) - 5.69n

First, simplify both sides of the equation: -3.69n + 22.7 = -9.3 - 5.69n

Next, let's get rid of the parentheses by performing the addition and subtraction inside: -3.69n + 22.7 = -0.6 - 5.69n

Now, let's group the terms containing 'n' on one side by adding 5.69n to both sides: -3.69n + 5.69n + 22.7 = -0.6 - 5.69n + 5.69n

Simplifying the equation further: 2n + 22.7 = -0.6

Next, isolate the variable 'n' by subtracting 22.7 from both sides: 2n + 22.7 - 22.7 = -0.6 - 22.7

Simplifying the equation: 2n = -23.3

Finally, solve for 'n' by dividing both sides by 2: n = -23.3 / 2

Simplifying the result: n = -11.65

Therefore, the solution to the equation is n = -11.65.
