Question

-0, 3(х+ 4)+ 4, 7= 0, 5( 8х- 7)- 1, 2( 5х-3)

Answer 1

Решение:

-0,3(х+4)+4,7=0,5(8х-7)-1,2(5х-3)

-0,3х-1,2+4,7=4х-3,5-6х+3,6

-0,3х-4х+6х=-3,5+3,6+1,2-4,7

1,7х=-3,4

х=-2

Ответ: х=-2

Answer 2

It looks like you've provided an equation that you would like to solve. Let's solve it step by step.

The equation you provided is:

-0.3(x + 4) + 4.7 = 0.5(8x - 7) - 1.2(5x - 3)

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

-0.3x - 0.3(4) + 4.7 = 0.5(8x) - 0.5(7) - 1.2(5x) + 1.2(3)

Simplify the equation further:

-0.3x - 1.2 + 4.7 = 4x - 3.5 - 6x + 3.6

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

-0.3x + 3.5 = 4x - 3.5 - 6x + 3.6

Combine the x-terms on the right side:

-0.3x + 3.5 = -2x + 3.6

Now, let's isolate the x-terms on one side and the constants on the other side:

-0.3x + 2x = 3.6 - 3.5

Combine the x-terms on the left side:

1.7x = 0.1

Now, solve for x by dividing both sides by 1.7:

x = 0.1 / 1.7

x ≈ 0.0588

So, the solution to the equation is approximately x ≈ 0.0588.
