Linear Equation
5 raruraru e ōrite ana ki:
\frac { 3 x + 5 } { 2 } - \frac { 2 x - 1 } { 4 } = 1
Tohaina
Kua tāruatia ki te papatopenga
2\left(3x+5\right)-\left(2x-1\right)=4
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 2,4.
6x+10-\left(2x-1\right)=4
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x+5.
6x+10-2x-\left(-1\right)=4
Hei kimi i te tauaro o 2x-1, kimihia te tauaro o ia taurangi.
6x+10-2x+1=4
Ko te tauaro o -1 ko 1.
4x+10+1=4
Pahekotia te 6x me -2x, ka 4x.
4x+11=4
Tāpirihia te 10 ki te 1, ka 11.
4x=4-11
Tangohia te 11 mai i ngā taha e rua.
4x=-7
Tangohia te 11 i te 4, ka -7.
x=\frac{-7}{4}
Whakawehea ngā taha e rua ki te 4.
x=-\frac{7}{4}
Ka taea te hautanga \frac{-7}{4} te tuhi anō ko -\frac{7}{4} mā te tango i te tohu tōraro.
