11 + (³/₈ × (- ⁵/₆) )х = - ⁴/₉
11 + (- ¹⁵/₄₈ х ) = - ⁴/₉
11 + (- ⁵/₁₆ х ) = - ⁴/₉
- ⁵/₁₆ х = - ⁴/₉ - 11
- ⁵/₁₆ х = - 11 ⁴/₉
х = (- 11 ⁴/₉ ) : ( - ⁵/₁₆ ) = (- ¹⁰³/₉ ) × ( - ¹⁶/₅ ) = ¹⁶⁴⁸/₄₅
х = 36 ²⁸/₄₅
=====================================
11 + ( ³/₈ × (-⁵/₆ ) ) × 36 ²⁸/₄₅= - ⁴/₉
11 + (- ⁵/₁₆) × ( ¹⁶⁴⁸/₉ ) = - ⁴/₉
11 + ( - ⁽¹ ˣ ¹⁰³ ⁾ / ₍₁ ₓ ₉ ₎ ) = - ⁴/₉
11 - 11 ⁴/₉ = - ⁴/₉
- (11 ⁴/₉ - 11) = - ⁴/₉
- ⁴/₉ = - ⁴/₉
