Answer 1

Solving for each equation:

A: True.

$\frac{n}{2} +3 *4 = \frac{n}{2}+12\\\\\frac{n}{2} + 12 = \frac{n}{2} + 12$

B: False.

$\frac{1}{3}z+\frac{2}{3}z * 9 = 9z\\\\\frac{1}{3} z+6z = 9z$

C: True, given that y = 1

$-8y +4.3y + 3.7 = 0\\\\-3.7y = -3.7$

D: True, given that b = 6.66667

$12-1.8b+1.8b=1.8b\\12 = 1.8b$

E: True.

$\frac{m}{8} + 7(\frac{m}{8} ) =m\\\\\frac{m}{8} + (\frac{7m}{8} )= m\\\\\\\frac{8m}{8} = m$
