Answer 2

Step-by-step explanation:

$= 12(x + 3) = 60 + 6 \\ = 12x + 36 = 66 \\ = 12x = 66 - 36 \\ = 12x = 30 \\ = x = \frac{30}{12}\: ans.$

$= = > (x - 12) \div 6 = 12 \\ = = > \frac{x - 12}{6} = 12 \\ = = > x - 12 = 12 \times 6 \\ = = > x = 72 + 12 \\ = = >x = 84 \: ans.$

$20 - (x + 5) = 20 - x - 5 \: ans.$

$18 \times (x + 4) \\ = 18 - x - 4 \: ans.$

$121 \div 7 + 89 \div 7 \\ = 17.28 + 12.71 \\ =29 . 99 \: ans.$

$= = > (x - 4) - 6 = 30 \\ = = > x + 4 - 6 = 30 \\ = = > x - 2 = 30 \\ = = > x = 32 \: ans$
