4x\times 3+3x\times 4+2x\times 5+12\left(\frac{x}{4}-8\right)\times 2=12\times 50^{4}
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4,6.
12x+3x\times 4+2x\times 5+12\left(\frac{x}{4}-8\right)\times 2=12\times 50^{4}
Whakareatia te 4 ki te 3, ka 12.
12x+12x+2x\times 5+12\left(\frac{x}{4}-8\right)\times 2=12\times 50^{4}
Whakareatia te 3 ki te 4, ka 12.
24x+2x\times 5+12\left(\frac{x}{4}-8\right)\times 2=12\times 50^{4}
Pahekotia te 12x me 12x, ka 24x.
24x+10x+12\left(\frac{x}{4}-8\right)\times 2=12\times 50^{4}
Whakareatia te 2 ki te 5, ka 10.
34x+12\left(\frac{x}{4}-8\right)\times 2=12\times 50^{4}
Pahekotia te 24x me 10x, ka 34x.
34x+24\left(\frac{x}{4}-8\right)=12\times 50^{4}
Whakareatia te 12 ki te 2, ka 24.
34x+24\times \frac{x}{4}-192=12\times 50^{4}
Whakamahia te āhuatanga tohatoha hei whakarea te 24 ki te \frac{x}{4}-8.
34x+6x-192=12\times 50^{4}
Whakakorea atu te tauwehe pūnoa nui rawa 4 i roto i te 24 me te 4.
40x-192=12\times 50^{4}
Pahekotia te 34x me 6x, ka 40x.
40x-192=12\times 6250000
Tātaihia te 50 mā te pū o 4, kia riro ko 6250000.
40x-192=75000000
Whakareatia te 12 ki te 6250000, ka 75000000.
40x=75000000+192
Me tāpiri te 192 ki ngā taha e rua.
40x=75000192
Tāpirihia te 75000000 ki te 192, ka 75000192.
x=\frac{75000192}{40}
Whakawehea ngā taha e rua ki te 40.
x=\frac{9375024}{5}
Whakahekea te hautanga \frac{75000192}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
