Datrys -1/3(-6-9x)+100x-(x+1)=3(33x+4)-2

$$- \frac { 1 } { 3 } ( - 6 - 9 x ) + 100 x - ( x + 1 ) = 3 ( 33 x + 4 ) - 2$$

Datrys ar gyfer x

$$x=3$$

Camau ar gyfer Datrys Hafaliad Llinol

Defnyddio’r briodwedd ddosbarthu i luosi -\frac{1}{3} â -6-9x.

$$-\frac{1}{3}\left(-6\right)-\frac{1}{3}\left(-9\right)x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Mynegwch -\frac{1}{3}\left(-6\right) fel ffracsiwn unigol.

$$\frac{-\left(-6\right)}{3}-\frac{1}{3}\left(-9\right)x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Lluosi -1 a -6 i gael 6.

$$\frac{6}{3}-\frac{1}{3}\left(-9\right)x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Rhannu 6 â 3 i gael 2.

$$2-\frac{1}{3}\left(-9\right)x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Mynegwch -\frac{1}{3}\left(-9\right) fel ffracsiwn unigol.

$$2+\frac{-\left(-9\right)}{3}x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Lluosi -1 a -9 i gael 9.

$$2+\frac{9}{3}x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Rhannu 9 â 3 i gael 3.

$$2+3x+100x-\left(x+1\right)=3\left(33x+4\right)-2$$

Cyfuno 3x a 100x i gael 103x.

$$2+103x-\left(x+1\right)=3\left(33x+4\right)-2$$

I ddod o hyd i wrthwyneb x+1, dewch o hyd i wrthwyneb pob term.

$$2+103x-x-1=3\left(33x+4\right)-2$$

Cyfuno 103x a -x i gael 102x.

$$2+102x-1=3\left(33x+4\right)-2$$

Tynnu 1 o 2 i gael 1.

$$1+102x=3\left(33x+4\right)-2$$

Defnyddio’r briodwedd ddosbarthu i luosi 3 â 33x+4.

$$1+102x=99x+12-2$$

Tynnu 2 o 12 i gael 10.

$$1+102x=99x+10$$

Tynnu 99x o'r ddwy ochr.

$$1+102x-99x=10$$

Cyfuno 102x a -99x i gael 3x.

$$1+3x=10$$

Tynnu 1 o'r ddwy ochr.

$$3x=10-1$$

Tynnu 1 o 10 i gael 9.

$$3x=9$$

Rhannu’r ddwy ochr â 3.

$$x=\frac{9}{3}$$

Rhannu 9 â 3 i gael 3.

$$x=3$$
