Question

4.5-3(0.4-2.1х)=-3.3+6х​

Answer 1

Ответ:

4,5-3(0,4-2,1х)=-3,3+6х

4,5-1,2+6,1х=-3,3+6х

6,1х-6=-3,3-4,5+1,2

0,1х=-6,6

х= -66

Answer 2

To solve this equation for the variable x, follow these steps:

Given equation: 4.5 - 3(0.4 - 2.1x) = -3.3 + 6x

Step 1: Distribute the -3 on the left side of the equation: 4.5 - 1.2 + 6.3x = -3.3 + 6x

Step 2: Combine like terms on both sides: 3.3 + 6.3x = -3.3 + 6x

Step 3: Move the terms involving x to one side of the equation and constants to the other side: 6.3x - 6x = -3.3 - 3.3

Step 4: Simplify the equation: 0.3x = -6.6

Step 5: Divide both sides by 0.3 to solve for x: x = -6.6 / 0.3 x = -22

So, the solution for the equation is x = -22.
