Whakaoti mō x, y, z, a
a=1
Tohaina
Kua tāruatia ki te papatopenga
x=\frac{15}{49}\times \frac{7}{5}
Whakaarohia te whārite tuatahi. Me whakarea ngā taha e rua ki te \frac{7}{5}, te tau utu o \frac{5}{7}.
x=\frac{3}{7}
Whakareatia te \frac{15}{49} ki te \frac{7}{5}, ka \frac{3}{7}.
x=\frac{3}{7} y=1 z=1 a=1
Kua oti te pūnaha te whakatau.
