2\left(x-11\right)+3\left(9+1\right)=-4
Whakaarohia te whārite tuarua. Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2.
2x-22+3\left(9+1\right)=-4
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-11.
2x-22+3\times 10=-4
Tāpirihia te 9 ki te 1, ka 10.
2x-22+30=-4
Whakareatia te 3 ki te 10, ka 30.
2x+8=-4
Tāpirihia te -22 ki te 30, ka 8.
2x=-4-8
Tangohia te 8 mai i ngā taha e rua.
2x=-12
Tangohia te 8 i te -4, ka -12.
x=\frac{-12}{2}
Whakawehea ngā taha e rua ki te 2.
x=-6
Whakawehea te -12 ki te 2, kia riro ko -6.
\frac{-6-1}{2}-\frac{y-1}{3}=-\frac{13}{30}
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
15\left(-6-1\right)-10\left(y-1\right)=-13
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3,30.
15\left(-7\right)-10\left(y-1\right)=-13
Tangohia te 1 i te -6, ka -7.
-105-10\left(y-1\right)=-13
Whakareatia te 15 ki te -7, ka -105.
-105-10y+10=-13
Whakamahia te āhuatanga tohatoha hei whakarea te -10 ki te y-1.
-95-10y=-13
Tāpirihia te -105 ki te 10, ka -95.
-10y=-13+95
Me tāpiri te 95 ki ngā taha e rua.
-10y=82
Tāpirihia te -13 ki te 95, ka 82.
y=\frac{82}{-10}
Whakawehea ngā taha e rua ki te -10.
y=-\frac{41}{5}
Whakahekea te hautanga \frac{82}{-10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
z=-6-1-2\left(-\frac{41}{5}\right)
Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
z=-7-2\left(-\frac{41}{5}\right)
Tangohia te 1 i te -6, ka -7.
z=-7+\frac{82}{5}
Whakareatia te -2 ki te -\frac{41}{5}, ka \frac{82}{5}.
z=\frac{47}{5}
Tāpirihia te -7 ki te \frac{82}{5}, ka \frac{47}{5}.
a=\frac{47}{5}
Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
x=-6 y=-\frac{41}{5} z=\frac{47}{5} a=\frac{47}{5}
Kua oti te pūnaha te whakatau.
