Answer 1

Пошаговое объяснение:

0,3(х-2)-0,2(х+4)=-2,9

0,3х-0,6-0,2х-0,8=-2,9

0,1х=-1,5

х=-15

Answer 2

Ответ:

$0.3(x - 2) - 0.2(x + 4) = - 2.9 \\ 0.3x - 0.6 - 0.2x - 0.8 = - 2.9 \\ 0.3x - 0.2x = - 2.9 + 0.6 + 0.8 \\ 0.1x = - 1.5 \\ x = - 15$

Answer 3

To solve the equation, let's simplify the expression on the left side and then solve for 'x'.

Given equation: 0.3(x - 2) - 0.2(x + 4) = -2.9

Step 1: Distribute the numbers inside the parentheses: 0.3x - 0.6 - 0.2x - 0.8 = -2.9

Step 2: Combine like terms: (0.3x - 0.2x) + (-0.6 - 0.8) = -2.9 0.1x - 1.4 = -2.9

Step 3: Isolate 'x' on one side of the equation. To do that, we'll add 1.4 to both sides of the equation: 0.1x - 1.4 + 1.4 = -2.9 + 1.4 0.1x = -1.5

Step 4: Now, to solve for 'x', we'll divide both sides by 0.1: x = -1.5 / 0.1 x = -15

So, the solution to the equation is x = -15.
