Yémalé yu am bènn deetxam

I. Yemale yu melni $a x+b=0$

$(a$ ak $b$ ay limum tjit la ñu)

• Su $a=0$ ak $b=0$ kon bépp limm ab sottal la.
  $\mathrm{S}=\{\mathrm{R}\}$
• Su $a \neq 0$ kon $x=\dfrac{-b}{a}$.
  $\mathrm{S}=\left\{\dfrac{-b}{a}\right\}$
• Su $a=0$ ak $b \neq 0$ kon amul sottal.
  $\rm S=\{\varnothing\}$

II. Yemale yu melni $(a x+b)(c x+d)=0$

Da ñuy jëfëndikoo jagle jii : $\rm A \times B=0$ mu ngi firi ne $\rm A=0$ wala $\rm B=0$
Da ngay sottali : $a x+b=0$ wala $c x+d=0$

III. Yemale yu melni $\dfrac{a}{x}=0$ ak $\dfrac{a}{x}=\dfrac{b}{c}$

Da ñuy jëfëndikoo jagle jii : $\dfrac{a}{b}=\dfrac{c}{d}$ mu ngi firi ne $a \times d=b \times c$.
