1474-22x=\left(72.6-x\right)\times 15
Whakamahia te āhuatanga tohatoha hei whakarea te 67-x ki te 22.
1474-22x=1089-15x
Whakamahia te āhuatanga tohatoha hei whakarea te 72.6-x ki te 15.
1474-22x+15x=1089
Me tāpiri te 15x ki ngā taha e rua.
1474-7x=1089
Pahekotia te -22x me 15x, ka -7x.
-7x=1089-1474
Tangohia te 1474 mai i ngā taha e rua.
-7x=-385
Tangohia te 1474 i te 1089, ka -385.
x=\frac{-385}{-7}
Whakawehea ngā taha e rua ki te -7.
x=55
Whakawehea te -385 ki te -7, kia riro ko 55.
