Kua tāruatia ki te papatopenga
y+4=-\frac{3}{2}x+3
Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{3}{2} ki te x-2.
-\frac{3}{2}x+3=y+4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{3}{2}x=y+4-3
Tangohia te 3 mai i ngā taha e rua.
-\frac{3}{2}x=y+1
Tangohia te 3 i te 4, ka 1.
\frac{-\frac{3}{2}x}{-\frac{3}{2}}=\frac{y+1}{-\frac{3}{2}}
Whakawehea ngā taha e rua o te whārite ki te -\frac{3}{2}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y+1}{-\frac{3}{2}}
Mā te whakawehe ki te -\frac{3}{2} ka wetekia te whakareanga ki te -\frac{3}{2}.
x=\frac{-2y-2}{3}
Whakawehe y+1 ki te -\frac{3}{2} mā te whakarea y+1 ki te tau huripoki o -\frac{3}{2}.
y+4=-\frac{3}{2}x+3
Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{3}{2} ki te x-2.
y=-\frac{3}{2}x+3-4
Tangohia te 4 mai i ngā taha e rua.
y=-\frac{3}{2}x-1
Tangohia te 4 i te 3, ka -1.
