Mae'r hafaliad yn y ffurf safonol.

$$\left(-9nosl^{2}\right)m=390000$$

Rhannu’r ddwy ochr â -9l^{2}ons.

$$\frac{\left(-9nosl^{2}\right)m}{-9nosl^{2}}=\frac{390000}{-9nosl^{2}}$$

Mae rhannu â -9l^{2}ons yn dad-wneud lluosi â -9l^{2}ons.

$$m=\frac{390000}{-9nosl^{2}}$$

Rhannwch 390000 â -9l^{2}ons.

$$m=-\frac{130000}{3nosl^{2}}$$
