Whakaoti i te {l}{5{(22*5-x)}+9*3x=350}{y=10}{z=y}{a=z}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { 5 {(22 \cdot 5 - x)} + 9 \cdot 3 x = 350 }\\ { y = 10 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c, d

$$d=10$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakareatia te 22 ki te 5, ka 110.

$$5\left(110-x\right)+9\times 3x=350$$

Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 110-x.

$$550-5x+9\times 3x=350$$

Whakareatia te 9 ki te 3, ka 27.

$$550-5x+27x=350$$

Pahekotia te -5x me 27x, ka 22x.

$$550+22x=350$$

Tangohia te 550 mai i ngā taha e rua.

$$22x=350-550$$

Tangohia te 550 i te 350, ka -200.

$$22x=-200$$

Whakawehea ngā taha e rua ki te 22.

$$x=\frac{-200}{22}$$

Whakahekea te hautanga \frac{-200}{22} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{100}{11}$$

Kua oti te pūnaha te whakatau.

$$x=-\frac{100}{11} y=10 z=10 a=10 b=10 c=10 d=10$$
