Whakaoti i te {l}{x=73}{y=7.5{(3x+4)}}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x = 73 }\\ { y = 7.5 {(3 x + 4)} }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=1672.5$$

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

$$y=7.5\left(3\times 73+4\right)$$

Whakareatia te 3 ki te 73, ka 219.

$$y=7.5\left(219+4\right)$$

Tāpirihia te 219 ki te 4, ka 223.

$$y=7.5\times 223$$

Whakareatia te 7.5 ki te 223, ka 1672.5.

$$y=1672.5$$

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

$$z=1672.5$$

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

$$a=1672.5$$

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

$$b=1672.5$$

Kua oti te pūnaha te whakatau.

$$x=73 y=1672.5 z=1672.5 a=1672.5 b=1672.5$$
