Answer 1

A)

$\large{x - 7 = 0}$

$\large{x = 0 + 7}$

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

________________________________

B)

$\large \frac{ x}{5} = 2$

$\large{x = 5 \times 2}$

$\large \boxed{ \boxed{{ \red{x = 10}}}}$

________________________________

C)

$\large2x + 6 = 12$

$\large2x = 12 - 6$

$\large{2x = 6}$

$\large{x = \frac{ 6}{2} }$

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

________________________________

D)

$\large{ - x + 8 = 0}$

$\large - x = 0 - 8$

$\large - x = - 8$

$\large \boxed{ \boxed{{ \red{x = 8}}}}$

________________________________

E)

$\large3x + 9 = 0$

$\large3x = 0 - 9$

$\large3x = - 9$

$\large x = - \frac{9}{3}$

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