Linear Equation
5 raruraru e ōrite ana ki:
3 ( x + 1 ) - 5 ( x + 10 ) = 9 ( x - 4 ) - 9 ( x - 8 )
Tohaina
Kua tāruatia ki te papatopenga
3x+3-5\left(x+10\right)=9\left(x-4\right)-9\left(x-8\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+1.
3x+3-5x-50=9\left(x-4\right)-9\left(x-8\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x+10.
-2x+3-50=9\left(x-4\right)-9\left(x-8\right)
Pahekotia te 3x me -5x, ka -2x.
-2x-47=9\left(x-4\right)-9\left(x-8\right)
Tangohia te 50 i te 3, ka -47.
-2x-47=9x-36-9\left(x-8\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x-4.
-2x-47=9x-36-9x+72
Whakamahia te āhuatanga tohatoha hei whakarea te -9 ki te x-8.
-2x-47=-36+72
Pahekotia te 9x me -9x, ka 0.
-2x-47=36
Tāpirihia te -36 ki te 72, ka 36.
-2x=36+47
Me tāpiri te 47 ki ngā taha e rua.
-2x=83
Tāpirihia te 36 ki te 47, ka 83.
x=\frac{83}{-2}
Whakawehea ngā taha e rua ki te -2.
x=-\frac{83}{2}
Ka taea te hautanga \frac{83}{-2} te tuhi anō ko -\frac{83}{2} mā te tango i te tohu tōraro.
