a)
3x - 8 + 3 = -3x - 1
Combine like terms:
3x - 5 = -3x - 1
Add $3x$ to both sides:
6x - 5 = -1
Add $5$ to both sides:
6x = 4
Divide by $6$:
x = \frac{4}{6} = \frac{2}{3}
b)
\frac{2}{3}m + 4 - 2m = \frac{1}{2} - \frac{1}{3}m
Combine like terms:
-\frac{4}{3}m+4=\frac{1}{2}-\frac{1}{3}m
Subtract $4$ from both sides:
-\frac{4}{3}m+\frac{1}{3}m=\frac{1}{2}-4
Convert $4$ to fraction:
-m=\frac{1}{2}-\frac{8}{2}
Simplify:
-m=-\frac{7}{2}
m=\frac{7}{2}
Combine like terms:
Add $3x$ to both sides:
Add $5$ to both sides:
Divide by $6$:
b)
Combine like terms:
Subtract $4$ from both sides:
Convert $4$ to fraction:
