E=-\left(-3x-x-2y+3\right)-\left(2x+y\right)-x-3+2-\left(x+y\right)
Hei kimi i te tauaro o 2y-3, kimihia te tauaro o ia taurangi.
E=3x-\left(-x\right)+2y-3-\left(2x+y\right)-x-3+2-\left(x+y\right)
Hei kimi i te tauaro o -3x-x-2y+3, kimihia te tauaro o ia taurangi.
E=3x-\left(-x\right)+2y-3-2x-y-x-3+2-\left(x+y\right)
Hei kimi i te tauaro o 2x+y, kimihia te tauaro o ia taurangi.
E=x-\left(-x\right)+2y-3-y-x-3+2-\left(x+y\right)
Pahekotia te 3x me -2x, ka x.
E=x-\left(-x\right)+y-3-x-3+2-\left(x+y\right)
Pahekotia te 2y me -y, ka y.
E=x-\left(-x\right)+y-6-x+2-\left(x+y\right)
Tangohia te 3 i te -3, ka -6.
E=x-\left(-x\right)+y-4-x-\left(x+y\right)
Tāpirihia te -6 ki te 2, ka -4.
E=x-\left(-x\right)+y-4-x-x-y
Hei kimi i te tauaro o x+y, kimihia te tauaro o ia taurangi.
E=-\left(-x\right)+y-4-x-y
Pahekotia te x me -x, ka 0.
E=-\left(-x\right)-4-x
Pahekotia te y me -y, ka 0.
E=x-4-x
Whakareatia te -1 ki te -1, ka 1.
E=-4
Pahekotia te x me -x, ka 0.
