Question

3x+1,2x+6,7x=1096,7x+1,9x+3,3x=38,08

Answer 1

10,9х=109
х=109/10,9
х=10
11,9х=38,08
x=38,08/11,9
х=3,2

Answer 2

To solve the equation 3x + 1.2x + 6.7x = 1096.7x + 1.9x + 3.3x = 38.08, we need to simplify and combine like terms on both sides of the equation.

First, let's simplify the left side of the equation by combining the like terms:

3x + 1.2x + 6.7x = (3 + 1.2 + 6.7)x = 11.9x

Now, let's simplify the right side of the equation by combining the like terms:

1096.7x + 1.9x + 3.3x = (1096.7 + 1.9 + 3.3)x = 1101.9x

So the equation becomes:

11.9x = 1101.9x + 38.08

To isolate the variable x, we can subtract 1101.9x from both sides of the equation:

11.9x - 1101.9x = 1101.9x - 1101.9x + 38.08 -1090x = 38.08

Next, we can divide both sides of the equation by -1090 to solve for x:

(-1090x) / -1090 = 38.08 / -1090 x = -0.0349 (rounded to four decimal places)

Therefore, the solution to the equation 3x + 1.2x + 6.7x = 1096.7x + 1.9x + 3.3x = 38.08 is x = -0.0349.
