Question

-0,4(3х-1)+8(0,3)=5-(3,8х+4)

Answer 1

Объяснение:

-0,4(3х-1)+8(0,3)=5-(3,8х+4)

-1,2х+0,4+2,4=5-3,8х-4

-1,2х+3,8х=5-4-0,4-2,4

2,6х= - 1,8

Х= - 1 4/5:2 3/5= - 9/5×5/13= - 9/13

Answer 2

To solve the equation -0.4(3x - 1) + 8(0.3) = 5 - (3.8x + 4), you'll need to simplify and isolate the variable x. Here's the step-by-step solution:

-0.4(3x - 1) + 8(0.3) = 5 - (3.8x + 4)

First, distribute the constants on both sides of the equation:

-1.2x + 0.4 + 2.4 = 5 - 3.8x - 4

Now, combine like terms on each side of the equation:

-1.2x + 2.8 = 1 - 3.8x

Next, move the terms involving x to one side of the equation and the constants to the other side:

-1.2x + 3.8x = 1 - 2.8

Now, add the x terms together:

2.6x = -1.8

Finally, solve for x by dividing both sides by 2.6:

x = -1.8 / 2.6

Now, simplify the fraction:

x = -0.6923 (rounded to four decimal places)

So, the solution to the equation is x ≈ -0.6923.
