Linear Equation
5(x-1)-(-2x)=8
Tohaina
Kua tāruatia ki te papatopenga
5x-5-\left(-2x\right)=8
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-1.
5x-5+2x=8
Ko te tauaro o -2x ko 2x.
7x-5=8
Pahekotia te 5x me 2x, ka 7x.
7x=8+5
Me tāpiri te 5 ki ngā taha e rua.
7x=13
Tāpirihia te 8 ki te 5, ka 13.
x=\frac{13}{7}
Whakawehea ngā taha e rua ki te 7.
