Therefore, the value of x is 7.375.


Hence verifed.

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
