Tohaina
Kua tāruatia ki te papatopenga
Q\left(2X-1\right)=45
Whakareatia ngā taha e rua o te whārite ki te 3.
2QX-Q=45
Whakamahia te āhuatanga tohatoha hei whakarea te Q ki te 2X-1.
\left(2X-1\right)Q=45
Pahekotia ngā kīanga tau katoa e whai ana i te Q.
\frac{\left(2X-1\right)Q}{2X-1}=\frac{45}{2X-1}
Whakawehea ngā taha e rua ki te 2X-1.
Q=\frac{45}{2X-1}
Mā te whakawehe ki te 2X-1 ka wetekia te whakareanga ki te 2X-1.
Q\left(2X-1\right)=45
Whakareatia ngā taha e rua o te whārite ki te 3.
2QX-Q=45
Whakamahia te āhuatanga tohatoha hei whakarea te Q ki te 2X-1.
2QX=45+Q
Me tāpiri te Q ki ngā taha e rua.
2QX=Q+45
He hanga arowhānui tō te whārite.
\frac{2QX}{2Q}=\frac{Q+45}{2Q}
Whakawehea ngā taha e rua ki te 2Q.
X=\frac{Q+45}{2Q}
Mā te whakawehe ki te 2Q ka wetekia te whakareanga ki te 2Q.
X=\frac{1}{2}+\frac{45}{2Q}
Whakawehe Q+45 ki te 2Q.
