Question

1,2x+(-x-1,9)=-2(0,4x-2,6)

Answer 1

12x-x-1,9=-2(0,4x-2,6)

1,2x-x-1,9=-0,8x+5,2

0,2x-1,9=-0,8x+5,2

0,2x+0,8x-1,9=5,2

0,2x+0,8x=5,2+1,9

x=5,2+1,9

x=7,1

Answer 2

Let's solve the equation step by step:

1,2x + (-x - 1.9) = -2(0.4x - 2.6)

Step 1: Distribute the -2 on the right side of the equation:

1.2x + (-x - 1.9) = -0.8x + 5.2

Step 2: Combine like terms on the left side of the equation:

(1.2x - x) - 1.9 = -0.8x + 5.2

0.2x - 1.9 = -0.8x + 5.2

Step 3: Move all the x terms to one side of the equation:

0.2x + 0.8x = 5.2 + 1.9

1x = 7.1

Step 4: Simplify the equation:

x = 7.1

So the solution to the equation is x = 7.1.
