Answer 1

Solution to Equation A: 2,3x + 1,6 - 1,5x - 0,3x = 0,8x + 1,3

To solve the equation 2,3x + 1,6 - 1,5x - 0,3x = 0,8x + 1,3, we can start by simplifying both sides of the equation.

On the left side, we have 2,3x - 1,5x - 0,3x, which simplifies to 0,5x.

On the right side, we have 0,8x + 1,3.

Now, we can rewrite the equation as 0,5x = 0,8x + 1,3.

To isolate the variable x, we can subtract 0,8x from both sides of the equation:

0,5x - 0,8x = 0,8x - 0,8x + 1,3

This simplifies to -0,3x = 1,3.

Next, we can divide both sides of the equation by -0,3 to solve for x:

(-0,3x) / -0,3 = 1,3 / -0,3

This gives us x = -4.333333333333333.

Therefore, the solution to equation A is x = -4.333333333333333.

Solution to Equation B: 1,4x + 1,1 - 0,5x + 0,6 = 0,9x + 1,8

To solve the equation 1,4x + 1,1 - 0,5x + 0,6 = 0,9x + 1,8, we can start by simplifying both sides of the equation.

On the left side, we have 1,4x - 0,5x, which simplifies to 0,9x.

On the right side, we have 0,9x + 1,8.

Now, we can rewrite the equation as 0,9x = 0,9x + 1,8.

To isolate the variable x, we can subtract 0,9x from both sides of the equation:

0,9x - 0,9x = 0,9x - 0,9x + 1,8

This simplifies to 0 = 1,8.

However, this equation has no solution because 0 cannot be equal to 1,8.

Therefore, the equation B has no solution.
