2.2x-4x-1.88=0.1x-2.583
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x+0.47.
-1.8x-1.88=0.1x-2.583
Pahekotia te 2.2x me -4x, ka -1.8x.
-1.8x-1.88-0.1x=-2.583
Tangohia te 0.1x mai i ngā taha e rua.
-1.9x-1.88=-2.583
Pahekotia te -1.8x me -0.1x, ka -1.9x.
-1.9x=-2.583+1.88
Me tāpiri te 1.88 ki ngā taha e rua.
-1.9x=-0.703
Tāpirihia te -2.583 ki te 1.88, ka -0.703.
x=\frac{-0.703}{-1.9}
Whakawehea ngā taha e rua ki te -1.9.
x=\frac{-703}{-1900}
Whakarohaina te \frac{-0.703}{-1.9} mā te whakarea i te taurunga me te tauraro ki te 1000.
x=\frac{37}{100}
Whakahekea te hautanga \frac{-703}{-1900} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -19.
