I ddod o hyd i wrthwyneb 4-2x, dewch o hyd i wrthwyneb pob term.
24-\left(2x-\left(3-4+2x\right)-1\right)
Gwrthwyneb -2x yw 2x.
24-\left(2x-\left(-1+2x\right)-1\right)
Tynnu 4 o 3 i gael -1.
24-\left(2x-\left(-1\right)-2x-1\right)
I ddod o hyd i wrthwyneb -1+2x, dewch o hyd i wrthwyneb pob term.
24-\left(2x+1-2x-1\right)
Gwrthwyneb -1 yw 1.
24-\left(1-1\right)
Cyfuno 2x a -2x i gael 0.
24-0
Tynnu 1 o 1 i gael 0.
24
Tynnu 0 o 24 i gael 24.
