3x+3=5\left(x+7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+1.
3x+3=5x+35
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+7.
3x+3-5x=35
Tangohia te 5x mai i ngā taha e rua.
-2x+3=35
Pahekotia te 3x me -5x, ka -2x.
-2x=35-3
Tangohia te 3 mai i ngā taha e rua.
-2x=32
Tangohia te 3 i te 35, ka 32.
x=\frac{32}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-16
Whakawehea te 32 ki te -2, kia riro ko -16.
