$$\left. \begin{array} { l } { \frac{1}{4} \cdot {(8 + 4 x)} + 3 = 2 }\\ { y = 5 x - 4 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakamahia te āhuatanga tohatoha hei whakarea te \frac{1}{4} ki te 8+4x.

$$2+x+3=2$$

Tāpirihia te 2 ki te 3, ka 5.

$$5+x=2$$

Tangohia te 5 mai i ngā taha e rua.

$$x=2-5$$

Tangohia te 5 i te 2, ka -3.

$$x=-3$$

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

$$y=5\left(-3\right)-4$$

Whakareatia te 5 ki te -3, ka -15.

$$y=-15-4$$

Tangohia te 4 i te -15, ka -19.

$$y=-19$$

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

$$z=-19$$

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

$$a=-19$$

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

$$b=-19$$

Kua oti te pūnaha te whakatau.

$$x=-3 y=-19 z=-19 a=-19 b=-19$$
