$$\frac{2ab^{2}}{\left(a-b\right)\left(a+b\right)}x+\left(-\frac{2ab^{2}}{\left(a-b\right)\left(a+b\right)}\right)x+\frac{2abc}{\left(a-b\right)\left(a+b\right)}y+\left(-\frac{2abc}{\left(b-a\right)\left(a+b\right)}\right)y=\frac{2ab}{a-b}-\frac{2ab}{a+b}$$

Tāpiri \frac{2ab^{2}x}{\left(a-b\right)\left(a+b\right)} ki te -\frac{2ab^{2}x}{\left(a-b\right)\left(a+b\right)}. Ka whakakore atu ngā kupu \frac{2ab^{2}x}{\left(a-b\right)\left(a+b\right)} me -\frac{2ab^{2}x}{\left(a-b\right)\left(a+b\right)}, ka toe he whārite me tētahi taurangi kotahi ka taea te whakaoti.

$$\frac{2abc}{\left(a-b\right)\left(a+b\right)}y+\left(-\frac{2abc}{\left(b-a\right)\left(a+b\right)}\right)y=\frac{2ab}{a-b}-\frac{2ab}{a+b}$$

Tāpiri \frac{2abcy}{\left(a-b\right)\left(a+b\right)} ki te -\frac{2bcay}{\left(b-a\right)\left(b+a\right)}.

$$\frac{4abc}{\left(a-b\right)\left(a+b\right)}y=\frac{2ab}{a-b}-\frac{2ab}{a+b}$$

Tāpiri \frac{2ab}{a-b} ki te -\frac{2ba}{a+b}.

$$\frac{4abc}{\left(a-b\right)\left(a+b\right)}y=\frac{4ab^{2}}{\left(a-b\right)\left(a+b\right)}$$

Whakawehea ngā taha e rua ki te \frac{4bca}{\left(a-b\right)\left(a+b\right)}.

$$y=\frac{b}{c}$$

Whakaurua te \frac{b}{c} mō y ki \left(-\frac{1}{a+b}+\frac{1}{a-b}\right)ax+\left(-\frac{1}{a+b}+\frac{1}{b-a}\right)cy=\frac{2a}{a+b}. I te mea kotahi anake te taurangi kei te whārite i puta, ka taea e koe te whakaoti mō x hāngai tonu.

$$\left(-\frac{1}{a+b}+\frac{1}{a-b}\right)ax+\left(-\frac{1}{a+b}+\frac{1}{b-a}\right)c\times \frac{b}{c}=\frac{2a}{a+b}$$

Whakareatia c\left(\left(b-a\right)^{-1}-\left(b+a\right)^{-1}\right) ki te \frac{b}{c}.

$$\left(-\frac{1}{a+b}+\frac{1}{a-b}\right)ax+\frac{2ab}{\left(b-a\right)\left(a+b\right)}=\frac{2a}{a+b}$$

Me tango \frac{2ab}{\left(b-a\right)\left(b+a\right)} mai i ngā taha e rua o te whārite.

$$\left(-\frac{1}{a+b}+\frac{1}{a-b}\right)ax=-\frac{2a^{2}}{\left(b-a\right)\left(a+b\right)}$$

Whakawehea ngā taha e rua ki te a\left(\left(a-b\right)^{-1}-\left(a+b\right)^{-1}\right).

$$x=\frac{a}{b}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{a}{b},y=\frac{b}{c}$$
