Whakaoti i te {l}{159.20x-5x+8=-5x}{y=0.00}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 159.20 x - 5 x + 8 = -5 x }\\ { y = 0.00 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=0$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Pahekotia te 159.2x me -5x, ka 154.2x.

$$154.2x+8=-5x$$

Me tāpiri te 5x ki ngā taha e rua.

$$154.2x+8+5x=0$$

Pahekotia te 154.2x me 5x, ka 159.2x.

$$159.2x+8=0$$

Tangohia te 8 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$159.2x=-8$$

Whakawehea ngā taha e rua ki te 159.2.

$$x=\frac{-8}{159.2}$$

Whakarohaina te \frac{-8}{159.2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{-80}{1592}$$

Whakahekea te hautanga \frac{-80}{1592} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$x=-\frac{10}{199}$$

Kua oti te pūnaha te whakatau.

$$x=-\frac{10}{199} y=0 z=0 a=0 b=0$$
