Question

0,8х – 3,6 = 5,4 – 1,2х

Answer 1

0.8x-3.6=5.4-1.2x
0.8x+1.2x=5.4+3.6
2x=9 /÷2
x=4.5

Answer 2

0.8×+1.2×=3.6+5.4
2×=9
×=9:2
×=4.5

Answer 3

To solve the equation 0.8x - 3.6 = 5.4 - 1.2x, you can follow these steps:

1. Add 1.2x to both sides of the equation to get the x terms on one side:

   0.8x + 1.2x - 3.6 = 5.4

2. Combine like terms on the left side:

   2x - 3.6 = 5.4

3. Add 3.6 to both sides to isolate the x term:

   2x - 3.6 + 3.6 = 5.4 + 3.6

4. Simplify:

   2x = 9.0

5. Finally, divide both sides by 2 to solve for x:

   2x / 2 = 9.0 / 2

   x = 4.5

So, the solution to the equation is x = 4.5.
