Tohaina
Kua tāruatia ki te papatopenga
3\left(a+b\right)=2\left(b+2\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
3a+3b=2\left(b+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te a+b.
3a+3b=2b+4
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te b+2.
3a=2b+4-3b
Tangohia te 3b mai i ngā taha e rua.
3a=-b+4
Pahekotia te 2b me -3b, ka -b.
3a=4-b
He hanga arowhānui tō te whārite.
\frac{3a}{3}=\frac{4-b}{3}
Whakawehea ngā taha e rua ki te 3.
a=\frac{4-b}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
3\left(a+b\right)=2\left(b+2\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
3a+3b=2\left(b+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te a+b.
3a+3b=2b+4
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te b+2.
3a+3b-2b=4
Tangohia te 2b mai i ngā taha e rua.
3a+b=4
Pahekotia te 3b me -2b, ka b.
b=4-3a
Tangohia te 3a mai i ngā taha e rua.
