5p-10+3\left(p+1\right)=25
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te p-2.
5p-10+3p+3=25
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te p+1.
8p-10+3=25
Pahekotia te 5p me 3p, ka 8p.
8p-7=25
Tāpirihia te -10 ki te 3, ka -7.
8p=25+7
Me tāpiri te 7 ki ngā taha e rua.
8p=32
Tāpirihia te 25 ki te 7, ka 32.
p=\frac{32}{8}
Whakawehea ngā taha e rua ki te 8.
p=4
Whakawehea te 32 ki te 8, kia riro ko 4.
