5x-2\left(5x-7\right)=3x+10
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,3,2.
5x-10x+14=3x+10
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 5x-7.
-5x+14=3x+10
Pahekotia te 5x me -10x, ka -5x.
-5x+14-3x=10
Tangohia te 3x mai i ngā taha e rua.
-8x+14=10
Pahekotia te -5x me -3x, ka -8x.
-8x=10-14
Tangohia te 14 mai i ngā taha e rua.
-8x=-4
Tangohia te 14 i te 10, ka -4.
x=\frac{-4}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{1}{2}
Whakahekea te hautanga \frac{-4}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -4.
