25,812-4.2d=31.311-5.5d
Bas_tet [7]

Let's solve your equation step-by-step.

25812−4.2d=31.311−5.5d

Step 1: Simplify both sides of the equation.

25812−4.2d=31.311−5.5d

25812+−4.2d=31.311+−5.5d

−4.2d+25812=−5.5d+31.311

Step 2: Add 5.5d to both sides.

−4.2d+25812+5.5d=−5.5d+31.311+5.5d

1.3d+25812=31.311

Step 3: Subtract 25812 from both sides.

1.3d+25812−25812=31.311−25812

1.3d=−25780.689

Step 4: Divide both sides by 1.3.

1.3d

1.3

=

−25780.689

1.3
