x%2F1.03+%2B+x%2F1.04%5E2+%2B+1%2F1.04%5E2+=+1+

x%2F1.03+%2B+x%2F1.0816+=+1+-+1%2F1.0816

x%2F1.03+%2B+x%2F1.0816+=+0.07544378698

find common denominator on the left

1.0816x%2F1.114048+%2B1.03x%2F1.114048+=+0.07544378698

%281.0816x%2B1.03x%29%2F1.114048+=+0.07544378698

1.0816x%2B1.03x=+0.07544378698%2A1.114048+

2.1116x=+0.08404799999749504

x=0.08404799999749504%2F2.1116

x ≈ 0.039803
