Whakaoti i te {l}{x=1/2*0}{y=4*5+10*5}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x = \frac{1}{2} \cdot 0 }\\ { y = 4 \cdot 5 + 10 \cdot 5 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=70$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakareatia te \frac{1}{2} ki te 0, ka 0.

$$x=0$$

Whakaarohia te whārite tuarua. Mahia ngā whakarea.

$$y=20+50$$

Tāpirihia te 20 ki te 50, ka 70.

$$y=70$$

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

$$z=70$$

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

$$a=70$$

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

$$b=70$$

Kua oti te pūnaha te whakatau.

$$x=0 y=70 z=70 a=70 b=70$$
