Answer 1

Explicación paso a paso:

$r)7(x + \frac{4}{2} ) = 14 \\ \\ 7(x + 2) = 14 \\ 7x + 14 = 14 \\ 7x = 14 - 14 \\ 7x = 0 \\ x = 0 \div 7 \\ x = 0$

$s)6x - \frac{36}{2} = 18 \\ \\ 6x - 18 = 18 \\ 6x = 18 + 18 \\ 6x = 36 \\ x = 36 \div 6 \\ x = 6$

$t)3x + 12 = 27 \\ 3x = 27 - 12 \\ 3x = 15 \\ x = 15 \div 3 \\ x = 5$

$m)9(x + \frac{3}{6} ) = 15 \\ \\ 9x + \frac{27}{6} = 15 \\ \\ 9x = 15 - \frac{27}{6} \\ \\ 9x = \frac{90 - 27}{6} \\ \\ 9x = \frac{63}{6} \\ \\ 9x = \frac{21}{2} \\ \\ x = \frac{21}{2} \div 9 \\ \\ x = \frac{21}{18} \\ \\ x = \frac{7}{6}$
