Whakaoti i te {l}{x/3*7=-5}{y=0*4}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x / 3 \cdot 7 = -5 }\\ { y = 0 \cdot 4 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=0$$

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 7.

$$\frac{x}{3}=-\frac{5}{7}$$

Me whakarea ngā taha e rua ki te 3.

$$x=-\frac{5}{7}\times 3$$

Whakareatia te -\frac{5}{7} ki te 3, ka -\frac{15}{7}.

$$x=-\frac{15}{7}$$

Whakaarohia te whārite tuarua. Whakareatia te 0 ki te 4, ka 0.

$$y=0$$

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

$$z=0$$

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

$$a=0$$

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

$$b=0$$

Kua oti te pūnaha te whakatau.

$$x=-\frac{15}{7} y=0 z=0 a=0 b=0$$
