Solving for each equation:
A: True.
[tex]\frac{n}{2} +3 *4 = \frac{n}{2}+12\\\\\frac{n}{2} + 12 = \frac{n}{2} + 12[/tex]
B: False.
[tex]\frac{1}{3}z+\frac{2}{3}z * 9 = 9z\\\\\frac{1}{3} z+6z = 9z[/tex]
C: True, given that y = 1
[tex]-8y +4.3y + 3.7 = 0\\\\-3.7y = -3.7[/tex]
D: True, given that b = 6.66667
[tex]12-1.8b+1.8b=1.8b\\12 = 1.8b[/tex]
E: True.
[tex]\frac{m}{8} + 7(\frac{m}{8} ) =m\\\\\frac{m}{8} + (\frac{7m}{8} )= m\\\\\\\frac{8m}{8} = m\\[/tex]
