30\left(5x-3\right)-15\left(2x-1\right)-70\left(3x-4\right)=10\left(2x-5\right)+21\left(3x-4\right)
Me whakarea ngā taha e rua o te whārite ki te 210, arā, te tauraro pātahi he tino iti rawa te kitea o 7,14,3,21,10.
150x-90-15\left(2x-1\right)-70\left(3x-4\right)=10\left(2x-5\right)+21\left(3x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 30 ki te 5x-3.
150x-90-30x+15-70\left(3x-4\right)=10\left(2x-5\right)+21\left(3x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -15 ki te 2x-1.
120x-90+15-70\left(3x-4\right)=10\left(2x-5\right)+21\left(3x-4\right)
Pahekotia te 150x me -30x, ka 120x.
120x-75-70\left(3x-4\right)=10\left(2x-5\right)+21\left(3x-4\right)
Tāpirihia te -90 ki te 15, ka -75.
120x-75-210x+280=10\left(2x-5\right)+21\left(3x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -70 ki te 3x-4.
-90x-75+280=10\left(2x-5\right)+21\left(3x-4\right)
Pahekotia te 120x me -210x, ka -90x.
-90x+205=10\left(2x-5\right)+21\left(3x-4\right)
Tāpirihia te -75 ki te 280, ka 205.
-90x+205=20x-50+21\left(3x-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te 2x-5.
-90x+205=20x-50+63x-84
Whakamahia te āhuatanga tohatoha hei whakarea te 21 ki te 3x-4.
-90x+205=83x-50-84
Pahekotia te 20x me 63x, ka 83x.
-90x+205=83x-134
Tangohia te 84 i te -50, ka -134.
-90x+205-83x=-134
Tangohia te 83x mai i ngā taha e rua.
-173x+205=-134
Pahekotia te -90x me -83x, ka -173x.
-173x=-134-205
Tangohia te 205 mai i ngā taha e rua.
-173x=-339
Tangohia te 205 i te -134, ka -339.
x=\frac{-339}{-173}
Whakawehea ngā taha e rua ki te -173.
x=\frac{339}{173}
Ka taea te hautanga \frac{-339}{-173} te whakamāmā ki te \frac{339}{173} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
