Datrys Q_{1}=600-4P_{A}-003M-12P_{A}+15G+6P_{B}+15N

$$Q _ { 1 } = 600 - 4 P _ { A } - 003 M - 12 P _ { A } + 15 G + 6 P _ { B } + 15 N$$

Datrys ar gyfer G

$$G=\frac{-15N+16P_{A}-6P_{B}+Q_{1}-600}{15}$$

Camau ar gyfer Datrys Hafaliad Llinol

Lluosi 0 a 0 i gael 0.

$$Q_{1}=600-4P_{A}-0\times 3M-12P_{A}+15G+6P_{B}+15N$$

Lluosi 0 a 3 i gael 0.

$$Q_{1}=600-4P_{A}-0M-12P_{A}+15G+6P_{B}+15N$$

Mae lluosi unrhyw beth â sero yn rhoi sero.

$$Q_{1}=600-4P_{A}-0-12P_{A}+15G+6P_{B}+15N$$

Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$600-4P_{A}-0-12P_{A}+15G+6P_{B}+15N=Q_{1}$$

Tynnu 600-4P_{A}-0 o'r ddwy ochr.

$$-12P_{A}+15G+6P_{B}+15N=Q_{1}-\left(600-4P_{A}-0\right)$$

Ychwanegu 12P_{A} at y ddwy ochr.

$$15G+6P_{B}+15N=Q_{1}-\left(600-4P_{A}-0\right)+12P_{A}$$

Tynnu 6P_{B} o'r ddwy ochr.

$$15G+15N=Q_{1}-\left(600-4P_{A}-0\right)+12P_{A}-6P_{B}$$

Tynnu 15N o'r ddwy ochr.

$$15G=Q_{1}-\left(600-4P_{A}-0\right)+12P_{A}-6P_{B}-15N$$

Aildrefnu'r termau.

$$15G=Q_{1}-\left(-4P_{A}+600\right)-15N-6P_{B}+12P_{A}$$

I ddod o hyd i wrthwyneb -4P_{A}+600, dewch o hyd i wrthwyneb pob term.

$$15G=Q_{1}+4P_{A}-600-15N-6P_{B}+12P_{A}$$

Cyfuno 4P_{A} a 12P_{A} i gael 16P_{A}.

$$15G=Q_{1}+16P_{A}-600-15N-6P_{B}$$

Mae'r hafaliad yn y ffurf safonol.

$$15G=-15N+16P_{A}-6P_{B}+Q_{1}-600$$

Rhannu’r ddwy ochr â 15.

$$\frac{15G}{15}=\frac{-15N+16P_{A}-6P_{B}+Q_{1}-600}{15}$$

Mae rhannu â 15 yn dad-wneud lluosi â 15.

$$G=\frac{-15N+16P_{A}-6P_{B}+Q_{1}-600}{15}$$

Rhannwch Q_{1}+16P_{A}-600-15N-6P_{B} â 15.

$$G=\frac{Q_{1}}{15}+\frac{16P_{A}}{15}-\frac{2P_{B}}{5}-N-40$$

Datrys ar gyfer M

$$M\in \mathrm{R}$$

$$Q_{1}=15G+15N-16P_{A}+6P_{B}+600$$
