Whakaoti mō x, y, z
z=\frac{25f_{7}}{2}
Tohaina
Kua tāruatia ki te papatopenga
y=f_{7}\times 0.5\left(3\times 7+4\right)
Whakakapia te 7 mō te x i te whārite y=f_{7}\times 0.5\left(3x+4\right).
y=12.5f_{7}
Me whakaoti te y=f_{7}\times 0.5\left(3\times 7+4\right) mō y.
z=12.5f_{7}
Whakakapia te 12.5f_{7} mō te y i te whārite z=y.
x=7 y=12.5f_{7} z=12.5f_{7}
Kua oti te pūnaha te whakatau.
