y=\frac{2\left(x+1\right)}{4}-\frac{-2x+2}{4}

Chun cothromóidí a shuimiú nó a dhealú, fairsingigh iad chun a n-ainmneoirí a mheaitseáil. Is é an t-iolrach is lú coitianta de 2 agus 4 ná 4. Méadaigh \frac{x+1}{2} faoi \frac{2}{2}.

y=\frac{2\left(x+1\right)-\left(-2x+2\right)}{4}

Tá an t-ainmneoir céanna ag \frac{2\left(x+1\right)}{4} agus \frac{-2x+2}{4} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.

y=\frac{2x+2+2x-2}{4}

Déan iolrúcháin in 2\left(x+1\right)-\left(-2x+2\right).

y=\frac{4x}{4}

Cumaisc téarmaí comhchosúla in: 2x+2+2x-2.

y=x

Cealaigh 4 agus 4.

x=y
