Question

3,2x-1,4x+0,8x-1,9x=-14,21

Answer 1

Ответ:-20,3

Пошаговое объяснение:

3,2x-1,4x+0,8x-1,9x=-14,21

1,8х+0,8x-1,9x=-14,21

2,6-1,9x=-14,21

0,7х=-14,21

х=-14,21:0,7

х=-20,3

Answer 2

To solve the equation 3.2x - 1.4x + 0.8x - 1.9x = -14.21, you can combine like terms on the left side of the equation and then solve for x:

3.2x - 1.4x + 0.8x - 1.9x = -14.21

Now, add and subtract the x terms on the left side:

(3.2 - 1.4 + 0.8 - 1.9)x = -14.21

Combine the coefficients of x:

(1.7x) = -14.21

Now, divide both sides by 1.7 to isolate x:

(1.7x) / 1.7 = (-14.21) / 1.7

x = -14.21 / 1.7

x ≈ -8.36

So, the solution to the equation is approximately x ≈ -8.36.
