Question

0,8-(1,5x-2)=0,8+4,5x

Answer 1

0,8-1,5х+2=0,8+4,5х
-1,5х-4,5х=0,8-0,8-2
-6х=-2
х=-2:(-6)
х=1/3

Answer 2

To solve the equation 0.8 - (1.5x - 2) = 0.8 + 4.5x, follow these steps:

1. Distribute the negative sign inside the parentheses on the left side of the equation:

0.8 - 1.5x + 2 = 0.8 + 4.5x

2. Combine like terms on both sides of the equation. You can do this by adding 1.5x to both sides and subtracting 0.8 from both sides:

0.8 + 2 - 0.8 - 1.5x + 1.5x = 0.8 + 4.5x + 1.5x - 0.8

This simplifies to:

2 - 1.5x = 5.3x

3. Now, isolate the variable x. First, add 1.5x to both sides:

2 - 1.5x + 1.5x = 5.3x + 1.5x

This simplifies to:

2 = 6.8x

4. Finally, divide both sides by 6.8 to solve for x:

2 / 6.8 = 6.8x / 6.8

x ≈ 0.2941

So, the solution to the equation is approximately x ≈ 0.2941.
