Whakaoti i te {l}{-7{(-37-5y)}-2y=y+3}{z=y}{text{Solvefor}atext{where}}{a=z}

$$\left. \begin{array} { l } { -7 {(-37 - 5 y)} - 2 y = y + 3 }\\ { z = y }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Whakaoti mō y, z, a

$$a=-8$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te -37-5y.

$$259+35y-2y=y+3$$

Pahekotia te 35y me -2y, ka 33y.

$$259+33y=y+3$$

Tangohia te y mai i ngā taha e rua.

$$259+33y-y=3$$

Pahekotia te 33y me -y, ka 32y.

$$259+32y=3$$

Tangohia te 259 mai i ngā taha e rua.

$$32y=3-259$$

Tangohia te 259 i te 3, ka -256.

$$32y=-256$$

Whakawehea ngā taha e rua ki te 32.

$$y=\frac{-256}{32}$$

Whakawehea te -256 ki te 32, kia riro ko -8.

$$y=-8$$

Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$z=-8$$

Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$a=-8$$

Kua oti te pūnaha te whakatau.

$$y=-8 z=-8 a=-8$$
