# 郁金香、玫瑰、菊花与甲乙丙

## 第一题

$$10 \times 郁金香 =$$ $$78 + 4 - 4 + 2 =$$ $$78 + 4 + ( - 4 + 2 ) =$$ $$78 + 4 - 2 =$$ $$78 + 2 = 80$$

$$郁金香 = 80 \div 10 = 8$$ $$玫瑰 = 3 \times 郁金香 - 2 = 3 \times 8 - 2 = 22$$ $$菊花 = 2 \times 玫瑰 + 4 = 2 \times 22 + 4 = 48$$

## 第二题

$1 \times 甲$$x 2 \times 甲 - 6$$2x - 6$
$3 \times 甲 + 4$$3x + 4 合计6 \times 甲 -6 + 4 = 178$$6x -6 + 4 = 178$

$$6 \times 甲 =$$ $$178 + 6 - 4 =$$ $$178 + 2 = 180$$

$$甲 = 180 \div 6 = 30$$ $$乙 = 2 \times 甲 - 6 = 2 \times 30 - 6 = 54$$ $$丙 = 3 \times 甲 + 4 = 3 \times 30 + 4 = 94$$
