Question

-(-1,3x+6,9)=-5*(0,1x+4)

Answer 1

-(-1,3х+6,9)=-5•(0,1х+4)
1,3х-6,9=-0,5х-20
1,3х+0,5х=6,9-20
1,8х=-13,1
х=-13,1:1,8
х=-7 5/18

Answer 2

To solve the given equation, let's perform the operation on both sides step by step.

The equation is:

-(-1, 3x + 6, 9) = -5 * (0, 1x + 4)

First, we need to apply the negation operation to the expression on the left side:

-(-1, 3x + 6, 9) = (1, -3x - 6, -9)

Now, we can perform the multiplication on the right side:

-5 * (0, 1x + 4) = (0 * -5, (1x + 4) * -5) = (0, -5x - 20)

The equation now becomes:

(1, -3x - 6, -9) = (0, -5x - 20)

Now, we can compare the corresponding components of both sides:

1 = 0 (This is not true) -3x - 6 = -5x - 20

To solve the equation -3x - 6 = -5x - 20, we'll isolate the x term:

Add 5x to both sides:

-3x - 5x - 6 = -5x - 5x - 20

-8x - 6 = -10x - 20

Add 10x to both sides:

-8x + 10x - 6 = -10x + 10x - 20

2x - 6 = -20

Add 6 to both sides:

2x - 6 + 6 = -20 + 6

2x = -14

Finally, divide by 2 to solve for x:

x = -14 / 2

x = -7

So the value of x that satisfies the equation is x = -7.
