5x+15-3=8\left(x+1\right)+2
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+3.
5x+12=8\left(x+1\right)+2
Tangohia te 3 i te 15, ka 12.
5x+12=8x+8+2
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x+1.
5x+12=8x+10
Tāpirihia te 8 ki te 2, ka 10.
5x+12-8x=10
Tangohia te 8x mai i ngā taha e rua.
-3x+12=10
Pahekotia te 5x me -8x, ka -3x.
-3x=10-12
Tangohia te 12 mai i ngā taha e rua.
-3x=-2
Tangohia te 12 i te 10, ka -2.
x=\frac{-2}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{2}{3}
Ka taea te hautanga \frac{-2}{-3} te whakamāmā ki te \frac{2}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
