ແກ້ m+5n=m-n/12m

$$m + 5 n = \frac { m - n } { 12 m }$$

ແກ້ສຳລັບ n

$$n=-\frac{m\left(12m-1\right)}{60m+1}$$

$$m\neq -\frac{1}{60}\text{ and }m\neq 0$$

ຂັ້ນຕອນສຳລັບການແກ້ສົມຜົນເສັ້ນຊື່

ຄູນທັງສອງຂ້າງຂອງສົມຜົນດ້ວຍ 12m.

$$12mm+5n\times 12m=m-n$$

ຄູນ m ກັບ m ເພື່ອໃຫ້ໄດ້ m^{2}.

$$12m^{2}+5n\times 12m=m-n$$

ຄູນ 5 ກັບ 12 ເພື່ອໃຫ້ໄດ້ 60.

$$12m^{2}+60nm=m-n$$

ເພີ່ມ n ໃສ່ທັງສອງດ້ານ.

$$12m^{2}+60nm+n=m$$

ລົບ 12m^{2} ອອກຈາກທັງສອງຂ້າງ.

$$60nm+n=m-12m^{2}$$

ຮວມທຸກຄຳສັບທີ່ມີ n.

$$\left(60m+1\right)n=m-12m^{2}$$

ຫານທັງສອງຂ້າງດ້ວຍ 60m+1.

$$\frac{\left(60m+1\right)n}{60m+1}=\frac{m\left(1-12m\right)}{60m+1}$$

ການຫານດ້ວຍ 60m+1 ຈະຍົກເລີກການຄູນດ້ວຍ 60m+1.

$$n=\frac{m\left(1-12m\right)}{60m+1}$$
