Answer 2

$\frac{1}{2} + 3x = 5$

$subtract \: \frac{1}{2} on \: both \: sides$

$\frac{1}{2} + 3x - \frac{1}{2} = 5 - \frac{1}{2}$

$3x = \frac{10 - 1}{2}$

$3x = \frac{9}{2}$

$divide \: 3 \: on \: both \: sides$

$\frac{ \cancel3x}{ \cancel3} = \frac{ {}^{ 3} \cancel9}{ 2} \times \frac{1}{ \cancel3}$

$x = \frac{3}{2}$

$x = 1.5$
