Solve for x 30=58log 20x+40/400x+50Solution
We have 30 = 58 log[ (20x + 40)/(400x + 50)] Therefore, log[ (20x + 40)/(400x + 50)] = 30/58 = 0.51724 ( approx.) Then (20x + 40)/(400x + 50) = 100.51724 = 3.29033 (approx.) Then, 3.29033 ( 400x + 50) = 20x + 40 or, 1316.13365x + 164.5165 = 20x + 40 or, ( 1316.13365 - 20x) = 40 - 164.5165 or, 1296.13365 x = - 124. 5165. Therefore, x = - 124. 5165 / 1296.13365 or, x = 0.09607 ( approximately on rounding off to 5 decimal places)
