Defnyddio’r briodwedd ddosbarthu i luosi 10 â x-7.

$$10x-70-8\left(x+5\right)=6\left(-5\right)+24$$

Defnyddio’r briodwedd ddosbarthu i luosi -8 â x+5.

$$10x-70-8x-40=6\left(-5\right)+24$$

Cyfuno 10x a -8x i gael 2x.

$$2x-70-40=6\left(-5\right)+24$$

Tynnu 40 o -70 i gael -110.

$$2x-110=6\left(-5\right)+24$$

Lluosi 6 a -5 i gael -30.

$$2x-110=-30+24$$

Adio -30 a 24 i gael -6.

$$2x-110=-6$$

Ychwanegu 110 at y ddwy ochr.

$$2x=-6+110$$

Adio -6 a 110 i gael 104.

$$2x=104$$

Rhannu’r ddwy ochr â 2.

$$x=\frac{104}{2}$$

Rhannu 104 â 2 i gael 52.

$$x=52$$
