3\left(5x-3\right)+96=4\left(2x+3\right)
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3.
15x-9+96=4\left(2x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5x-3.
15x+87=4\left(2x+3\right)
Tāpirihia te -9 ki te 96, ka 87.
15x+87=8x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2x+3.
15x+87-8x=12
Tangohia te 8x mai i ngā taha e rua.
7x+87=12
Pahekotia te 15x me -8x, ka 7x.
7x=12-87
Tangohia te 87 mai i ngā taha e rua.
7x=-75
Tangohia te 87 i te 12, ka -75.
x=\frac{-75}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{75}{7}
Ka taea te hautanga \frac{-75}{7} te tuhi anō ko -\frac{75}{7} mā te tango i te tohu tōraro.
