Tohaina
Kua tāruatia ki te papatopenga
3\times \frac{3}{4}x-\frac{7}{2}x=3x+2
Whakawehea te 6 ki te 2, kia riro ko 3.
\frac{3\times 3}{4}x-\frac{7}{2}x=3x+2
Tuhia te 3\times \frac{3}{4} hei hautanga kotahi.
\frac{9}{4}x-\frac{7}{2}x=3x+2
Whakareatia te 3 ki te 3, ka 9.
-\frac{5}{4}x=3x+2
Pahekotia te \frac{9}{4}x me -\frac{7}{2}x, ka -\frac{5}{4}x.
-\frac{5}{4}x-3x=2
Tangohia te 3x mai i ngā taha e rua.
-\frac{17}{4}x=2
Pahekotia te -\frac{5}{4}x me -3x, ka -\frac{17}{4}x.
x=2\left(-\frac{4}{17}\right)
Me whakarea ngā taha e rua ki te -\frac{4}{17}, te tau utu o -\frac{17}{4}.
x=\frac{2\left(-4\right)}{17}
Tuhia te 2\left(-\frac{4}{17}\right) hei hautanga kotahi.
x=\frac{-8}{17}
Whakareatia te 2 ki te -4, ka -8.
x=-\frac{8}{17}
Ka taea te hautanga \frac{-8}{17} te tuhi anō ko -\frac{8}{17} mā te tango i te tohu tōraro.
