Solve the system of equations x/6+y/8 =14 and x/8+y/6 =14

פתרון

\frac{x}{6} + \frac{y}{8} = 14, \frac{x}{8} + \frac{y}{6} = 14

פתרון

x = 48, y = 48

צעדי פתרון

[\frac{x}{6} + \frac{y}{8} = 14 \frac{x}{8} + \frac{y}{6} = 14]

\frac{x}{6} + \frac{y}{8} = 14

עבור

x

בודד את:

x = 84 - \frac{3 y}{4}

x = 84 - \frac{3 y}{4}

החלף

[\frac{84 - \frac{3 y}{4}}{8} + \frac{y}{6} = 14]

פשט

[\frac{1008 + 7 y}{96} = 14]

\frac{1008 + 7 y}{96} = 14

עבור

y

בודד את:

y = 48

x = 84 - \frac{3 y}{4}

עבור

y = 48

החלף

x = 84 - \frac{3 \cdot 48}{4}

84 - \frac{3 \cdot 48}{4} = 48

x = 48

:הפתרונות למערכת המשוואות הם
