Answer 2

Answer:

Let's study another example.

Let's study another example.Evaluate \dfrac13a-1-\dfrac12b31a−1−21bstart fraction, 1, divided by, 3, end fraction, a, minus, 1, minus, start fraction, 1, divided by, 2, end fraction, b when a=12a=12a, equals, 12 and b=6b=6b, equals, 6.

Let's study another example.Evaluate \dfrac13a-1-\dfrac12b31a−1−21bstart fraction, 1, divided by, 3, end fraction, a, minus, 1, minus, start fraction, 1, divided by, 2, end fraction, b when a=12a=12a, equals, 12 and b=6b=6b, equals, 6.\begin{aligned} &\phantom{=}\dfrac13\blueD a-1-\dfrac12\goldD b \\\\ &= \dfrac13 \cdot \blueD {12}-1-\dfrac12 \cdot \goldD 6~~~~~~~~\text{Replace }\blueD{a} \text{ with } \blueD{12}\text{ and } \goldD b \text{ with } \goldD 6\text{.} \\\\ &=4 - 1 - 3 \\\\ &=0 \end{aligned}=31a−1−21b=31⋅12−1−21⋅6        Replace a with 12 and b with 6.=4−1−3=0
