Whakaoti i te {l}{{(2*37+x)}-7*3=2}{y=77}{z=y}{a=z}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { {(2 \cdot 37 + x)} - 7 \cdot 3 = 2 }\\ { y = 77 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c, d

$$d=77$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakareatia te 2 ki te 37, ka 74.

$$74+x-7\times 3=2$$

Whakareatia te 7 ki te 3, ka 21.

$$74+x-21=2$$

Tangohia te 21 i te 74, ka 53.

$$53+x=2$$

Tangohia te 53 mai i ngā taha e rua.

$$x=2-53$$

Tangohia te 53 i te 2, ka -51.

$$x=-51$$

Kua oti te pūnaha te whakatau.

$$x=-51 y=77 z=77 a=77 b=77 c=77 d=77$$
