Whakaoti i te {l}{2{(x+1)}=-3}{y={(x+6)}}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 2 {(x + 1)} = -3 }\\ { y = {(x + 6)} }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b = \frac{7}{2} = 3\frac{1}{2} = 3.5$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 2.

$$x+1=-\frac{3}{2}$$

Tangohia te 1 mai i ngā taha e rua.

$$x=-\frac{3}{2}-1$$

Tangohia te 1 i te -\frac{3}{2}, ka -\frac{5}{2}.

$$x=-\frac{5}{2}$$

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

$$y=-\frac{5}{2}+6$$

Tāpirihia te -\frac{5}{2} ki te 6, ka \frac{7}{2}.

$$y=\frac{7}{2}$$

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

$$z=\frac{7}{2}$$

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

$$a=\frac{7}{2}$$

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

$$b=\frac{7}{2}$$

Kua oti te pūnaha te whakatau.

$$x=-\frac{5}{2} y=\frac{7}{2} z=\frac{7}{2} a=\frac{7}{2} b=\frac{7}{2}$$
