Whakaoti mō x, y, z, a, b
b=5
Tohaina
Kua tāruatia ki te papatopenga
x\times 81+4x=-12
Whakaarohia te whārite tuatahi. Whakareatia ngā taha e rua o te whārite ki te -4.
85x=-12
Pahekotia te x\times 81 me 4x, ka 85x.
x=-\frac{12}{85}
Whakawehea ngā taha e rua ki te 85.
x=-\frac{12}{85} y=5 z=5 a=5 b=5
Kua oti te pūnaha te whakatau.
