-2x-3\left(-y\right)+12-2-3x\left(-2y+1\right)-\left(-y\right)\left(4-5x\right)

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te -y-4.

-2x+3y+12-2-3x\left(-2y+1\right)-\left(-y\right)\left(4-5x\right)

Whakareatia te -3 ki te -1, ka 3.

-2x+3y+10-3x\left(-2y+1\right)-\left(-y\right)\left(4-5x\right)

Tangohia te 2 i te 12, ka 10.

-2x+3y+10-3x\left(-2y+1\right)-\left(4\left(-y\right)-5\left(-y\right)x\right)

Whakamahia te āhuatanga tohatoha hei whakarea te -y ki te 4-5x.
