Answer 1

$\large{a)3x = 15}$

$\large{x = 15 \div 3}$

$\large\boxed{\red{{x = 5}}}$

______________________________________

$\large{b)2x = 14}$

$\large{x = 14 \div 2}$

$\large\boxed{\red{{x = 7}}}$

______________________________________

$\large{c)4x = - 12}$

$\large{x = - 12 \div 4}$

$\large\boxed{\red{{x = - 3}}}$

______________________________________

$\large{d)7x = - 21}$

$\large{x = - 21 \div 7}$

$\large\boxed{\red{{x = - 3}}}$

______________________________________

$\large{e)13x = 13}$

$\large{x = 13 \div 13}$

$\large\boxed{\red{{x = 1}}}$

______________________________________

$\large{f)9x = - 9}$

$\large{x = - 9 \div 9}$

$\large\boxed{\red{{x = - 1}}}$

______________________________________

$\large{g)25x = 0}$

$\large{x = 0 \div 25}$

$\large\boxed{\red{{x = 0}}}$

______________________________________

$\large{h)35x = - 105}$

$\large{x = - 105 \div 35}$

$\large\boxed{\red{{x = - 3}}}$

______________________________________

$\large{i)4x = 1}$

$\large\boxed{\red{{x = \frac{1}{4} }}}$

______________________________________

$\large{j)36x = 12}$

$\large\boxed{\red{{x = \frac{12}{36} }}}$

______________________________________

$\large{k)21 = 3 x}$

$\large{3x = 21}$

$\large{x = 21 \div 3}$

$\large\boxed{\red{{x = 7}}}$

______________________________________

$\large{l)84 = 6x}$

$\large{6x = 84}$

$\large{x = 84 \div 6}$

$\large\boxed{\red{{x = 14}}}$
