3x-6-40x+28=-87
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te 10x-7.
-37x-6+28=-87
Pahekotia te 3x me -40x, ka -37x.
-37x+22=-87
Tāpirihia te -6 ki te 28, ka 22.
-37x=-87-22
Tangohia te 22 mai i ngā taha e rua.
-37x=-109
Tangohia te 22 i te -87, ka -109.
x=\frac{-109}{-37}
Whakawehea ngā taha e rua ki te -37.
x=\frac{109}{37}
Ka taea te hautanga \frac{-109}{-37} te whakamāmā ki te \frac{109}{37} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
