2\left(85x-7x-14\right)>3\left(4-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te x+2.
2\left(78x-14\right)>3\left(4-x\right)
Pahekotia te 85x me -7x, ka 78x.
156x-28>3\left(4-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 78x-14.
156x-28>12-3x
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 4-x.
156x-28+3x>12
Me tāpiri te 3x ki ngā taha e rua.
159x-28>12
Pahekotia te 156x me 3x, ka 159x.
159x>12+28
Me tāpiri te 28 ki ngā taha e rua.
159x>40
Tāpirihia te 12 ki te 28, ka 40.
x>\frac{40}{159}
Whakawehea ngā taha e rua ki te 159. I te mea he tōrunga te 159, kāore e huri te ahunga koreōrite.
