Step 1
The given equation is 0.10d+0.25(d+7)=5.25.
The equation 0.10d+0.25(d+7)=5.25 can be solved as follows.
We multiply the decimal number by 100 to shift the decimal towards right hand side by two place.
Step 2
For clearing the decimals we multiply each term by 100.
100×0.10d+100×0.25(d+7)=100×5.25
10d+25(d+7)=525
10d+25d+175=525
Subtract 175 on sides.
10d+25d+175175=525175
35d=350
Divide both sides by 35.
35d35=35035
 d=10
Therefore, d=10 is the solution of 0.10d+0.25(d+7)=5.25.
