Linear Equation
5 raruraru e ōrite ana ki:
\frac { 3 p - 2 } { 7 } - \frac { p - 2 } { 4 } = 2
Tohaina
Kua tāruatia ki te papatopenga
4\left(3p-2\right)-7\left(p-2\right)=56
Me whakarea ngā taha e rua o te whārite ki te 28, arā, te tauraro pātahi he tino iti rawa te kitea o 7,4.
12p-8-7\left(p-2\right)=56
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3p-2.
12p-8-7p+14=56
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te p-2.
5p-8+14=56
Pahekotia te 12p me -7p, ka 5p.
5p+6=56
Tāpirihia te -8 ki te 14, ka 6.
5p=56-6
Tangohia te 6 mai i ngā taha e rua.
5p=50
Tangohia te 6 i te 56, ka 50.
p=\frac{50}{5}
Whakawehea ngā taha e rua ki te 5.
p=10
Whakawehea te 50 ki te 5, kia riro ko 10.
