10\left(3x+2\right)-25\left(5x-7\right)=2\left(-8x+3\right)
Me whakarea ngā taha e rua o te whārite ki te 50, arā, te tauraro pātahi he tino iti rawa te kitea o 5,2,25.
30x+20-25\left(5x-7\right)=2\left(-8x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te 3x+2.
30x+20-125x+175=2\left(-8x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -25 ki te 5x-7.
-95x+20+175=2\left(-8x+3\right)
Pahekotia te 30x me -125x, ka -95x.
-95x+195=2\left(-8x+3\right)
Tāpirihia te 20 ki te 175, ka 195.
-95x+195=-16x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te -8x+3.
-95x+195+16x=6
Me tāpiri te 16x ki ngā taha e rua.
-79x+195=6
Pahekotia te -95x me 16x, ka -79x.
-79x=6-195
Tangohia te 195 mai i ngā taha e rua.
-79x=-189
Tangohia te 195 i te 6, ka -189.
x=\frac{-189}{-79}
Whakawehea ngā taha e rua ki te -79.
x=\frac{189}{79}
Ka taea te hautanga \frac{-189}{-79} te whakamāmā ki te \frac{189}{79} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
