Kua tāruatia ki te papatopenga
54x+65\left(0-3x\right)=86
Whakareatia te 0 ki te 4, ka 0.
54x+65\left(-3\right)x=86
Ko te tau i tāpiria he kore ka hua koia tonu.
54x-195x=86
Whakareatia te 65 ki te -3, ka -195.
-141x=86
Pahekotia te 54x me -195x, ka -141x.
x=\frac{86}{-141}
Whakawehea ngā taha e rua ki te -141.
x=-\frac{86}{141}
Ka taea te hautanga \frac{86}{-141} te tuhi anō ko -\frac{86}{141} mā te tango i te tohu tōraro.
