Syms x y z b e
Eq1=(e - 19.425) * x + 8.42 * b - 400;
Eq2=(e - 19.425) * y + 81.79 * b - 3200;
Eq3=(e - 19.425) * z - 70.
Eq4 x * y=0.0368 * 0.0333 * y ^ 2 + 5.633 * y 106.8857 + 6.2908 * 0.0351 * x x ^ 2 - z;
"=b + e - 63.75;
A=solve (eq1, eq2, eq3, eq4, ", x, y, z, b, e)
A=

B: [2 x1 sym]
E: [2 x1 sym]
X: [2 x1 sym]
Y: [2 x1 sym]
Z: [2 x1 sym]

(53567 * 6194453222828443095725179342147819 ^ (1/2))/944630750721331953664 + 7702778382938654/900870085450489
7702778382938654/900870085450489 - (53567 * 6194453222828443095725179342147819 ^ (1/2))/944630750721331953664
