Linear Equation
5 raruraru e ōrite ana ki:
\frac { x } { 7 } - \frac { 3 x - 1 } { 5 } + 3 = 0
Tohaina
Kua tāruatia ki te papatopenga
5x-7\left(3x-1\right)+105=0
Me whakarea ngā taha e rua o te whārite ki te 35, arā, te tauraro pātahi he tino iti rawa te kitea o 7,5.
5x-21x+7+105=0
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te 3x-1.
-16x+7+105=0
Pahekotia te 5x me -21x, ka -16x.
-16x+112=0
Tāpirihia te 7 ki te 105, ka 112.
-16x=-112
Tangohia te 112 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-112}{-16}
Whakawehea ngā taha e rua ki te -16.
x=7
Whakawehea te -112 ki te -16, kia riro ko 7.
