Whakaoti i te {l}{4/{(frac{3*{(7)}+5}{7})}=x}{y=10}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 4 / {(\frac{3 \cdot {(7)} + 5}{7})} = x }\\ { y = 10 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=10$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehe 4 ki te \frac{3\times 7+5}{7} mā te whakarea 4 ki te tau huripoki o \frac{3\times 7+5}{7}.

$$\frac{4\times 7}{3\times 7+5}=x$$

Whakareatia te 4 ki te 7, ka 28.

$$\frac{28}{3\times 7+5}=x$$

Whakareatia te 3 ki te 7, ka 21.

$$\frac{28}{21+5}=x$$

Tāpirihia te 21 ki te 5, ka 26.

$$\frac{28}{26}=x$$

Whakahekea te hautanga \frac{28}{26} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{14}{13}=x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x=\frac{14}{13}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{14}{13} y=10 z=10 a=10 b=10$$
