求解 {l}{sqrt{233y}=30+z}{y=x+8}{z=3+x}

$$\left. \begin{array}{l}{ \sqrt { 233 y } = 30 + z }\\{ y = x + 8 }\\{ z = 3 + x }\end{array} \right.$$

求解 y, z, x 的值

$$x=\frac{167-\sqrt{30989}}{2}\approx -4.518463972\text{, }y=\frac{183-\sqrt{30989}}{2}\approx 3.481536028\text{, }z=\frac{173-\sqrt{30989}}{2}\approx -1.518463972$$

$$x=\frac{\sqrt{30989}+167}{2}\approx 171.518463972\text{, }y=\frac{\sqrt{30989}+183}{2}\approx 179.518463972\text{, }z=\frac{\sqrt{30989}+173}{2}\approx 174.518463972$$
