Question

4) -6,7x + (-3,5 - 3,3x) = 6,5.​

Answer 1

-6,7x+(-3,5-3,3x)=6,5

-6,7x-3,5-3,3x=6,5

-10x-3,3x=6,5

-10x=6,5+3,5

-10x=10

x= -1

Answer 2

Ответ:

-1

Пошаговое объяснение:

-6,7x-3,5-3,3x=6,5

-6,7x-3,3x=6,5+3,5. коли переносимо міняємо знаки

-10x=10

x=10÷(-10)

x=-1

Answer 3

To solve the equation -6 + 7x - (3.5 - 3.3x) = 6.5, you can follow these steps:

1. First, remove the parentheses by distributing the negative sign inside the second parentheses:

-6 + 7x - 3.5 + 3.3x = 6.5

2. Combine like terms on both sides of the equation. Combine the constants (-6 and -3.5) and the x terms (7x and 3.3x):

(7x + 3.3x) - (6 + 3.5) = 6.5

10.3x - 9.5 = 6.5

3. Add 9.5 to both sides of the equation to isolate the term with x:

10.3x - 9.5 + 9.5 = 6.5 + 9.5

10.3x = 16

4. Finally, divide both sides by 10.3 to solve for x:

(10.3x)/10.3 = 16/10.3

x ≈ 1.5534

So, the solution to the equation is approximately x ≈ 1.5534.
