3\left(4x+1\right)=5\left(x-5\right)
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 5,3.
12x+3=5\left(x-5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4x+1.
12x+3=5x-25
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-5.
12x+3-5x=-25
Tangohia te 5x mai i ngā taha e rua.
7x+3=-25
Pahekotia te 12x me -5x, ka 7x.
7x=-25-3
Tangohia te 3 mai i ngā taha e rua.
7x=-28
Tangohia te 3 i te -25, ka -28.
x=\frac{-28}{7}
Whakawehea ngā taha e rua ki te 7.
x=-4
Whakawehea te -28 ki te 7, kia riro ko -4.
