Linear Equation
3x-2(3x+4)=10
Tohaina
Kua tāruatia ki te papatopenga
3x-6x-8=10
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 3x+4.
-3x-8=10
Pahekotia te 3x me -6x, ka -3x.
-3x=10+8
Me tāpiri te 8 ki ngā taha e rua.
-3x=18
Tāpirihia te 10 ki te 8, ka 18.
x=\frac{18}{-3}
Whakawehea ngā taha e rua ki te -3.
x=-6
Whakawehea te 18 ki te -3, kia riro ko -6.
