32x+56+6\left(8x+10\right)=516
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 4x+7.
32x+56+48x+60=516
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 8x+10.
80x+56+60=516
Pahekotia te 32x me 48x, ka 80x.
80x+116=516
Tāpirihia te 56 ki te 60, ka 116.
80x=516-116
Tangohia te 116 mai i ngā taha e rua.
80x=400
Tangohia te 116 i te 516, ka 400.
x=\frac{400}{80}
Whakawehea ngā taha e rua ki te 80.
x=5
Whakawehea te 400 ki te 80, kia riro ko 5.
