Kua tāruatia ki te papatopenga
4\left(-x\right)-4+5x-2=-2x-x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te -x-1.
4\left(-x\right)-6+5x=-2x-x
Tangohia te 2 i te -4, ka -6.
4\left(-x\right)-6+5x=-3x
Pahekotia te -2x me -x, ka -3x.
4\left(-x\right)-6+5x+3x=0
Me tāpiri te 3x ki ngā taha e rua.
4\left(-x\right)-6+8x=0
Pahekotia te 5x me 3x, ka 8x.
4\left(-x\right)+8x=6
Me tāpiri te 6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
-4x+8x=6
Whakareatia te 4 ki te -1, ka -4.
4x=6
Pahekotia te -4x me 8x, ka 4x.
x=\frac{6}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{3}{2}
Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
