4\left(x+1\right)-3\left(x-4\right)=5x
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 3,4,12.
4x+4-3\left(x-4\right)=5x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+1.
4x+4-3x+12=5x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-4.
x+4+12=5x
Pahekotia te 4x me -3x, ka x.
x+16=5x
Tāpirihia te 4 ki te 12, ka 16.
x+16-5x=0
Tangohia te 5x mai i ngā taha e rua.
-4x+16=0
Pahekotia te x me -5x, ka -4x.
-4x=-16
Tangohia te 16 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-16}{-4}
Whakawehea ngā taha e rua ki te -4.
x=4
Whakawehea te -16 ki te -4, kia riro ko 4.
