how would i solve for d/E (D/E + 1) × 0.15 = 0.2175 + 0.06× (D/E)

Assuming d/E is the same as D/E then the equation can be written as:

 

0.15*(D/E) + 0.15 = 0.2175 +0.06*(D/E)

 

Subtract 0.06(D/E) from both sides:

0.09*(D/E) + 0.15 = 0.2175

 

Subtract 0.15 from both sides:

0.09*(D/E) = 0.0675

 

Divide both sides by 0.09:

D/E = 0.75
