Question

0.4(x-3)-0.3(x+2)=-3.6

Answer 1

$\displaystyle \tt 0,4(x-3)-0,3(x+2)=-3,6\\ \displaystyle \tt 0,4x-1,2-0,3x-0,6=-3,6\\ \displaystyle \tt 0,1x-1,8=-3,6\\ \displaystyle \tt 0,1x=-3,6+1,8\\ \displaystyle \tt 0,1x=-1,8\\ \displaystyle \tt x=-1,8\div0,1\\ \displaystyle \tt x=-18\div1\\ \displaystyle \tt \bold{x=-18}$

Answer 2

Ответ:

Пошаговое объяснение:

0.4х-1.2-0.3х-0.6=-3.6

0.4х-0.3х=1.2+0.6-3.6

0.1х=-1.8

х=-1.8:0.1

х=-18

Answer 3

To solve the equation 0.4(x-3) - 0.3(x+2) = -3.6, you can follow these steps:

1. Distribute the constants on the left side of the equation: 0.4x - 1.2 - 0.3x - 0.6 = -3.6

2. Combine like terms on the left side of the equation: (0.4x - 0.3x) - (1.2 + 0.6) = -3.6 0.1x - 1.8 = -3.6

3. Add 1.8 to both sides of the equation to isolate the term with x: 0.1x - 1.8 + 1.8 = -3.6 + 1.8 0.1x = -1.8

4. Finally, divide both sides by 0.1 to solve for x: (0.1x) / 0.1 = (-1.8) / 0.1 x = -18

So, the solution to the equation is x = -18.
