Answer
a) $x=2$
b)$x=\frac{5}{2}$
c)$x=-2$
d)$x=-1$
Work Step by Step
a) Add $1$ to both sides and divide.
$3x-1=5$
$3x=6$
$x=2$
b) Subtract $3$ from both sides and divide.
$2x+3=8$
$2x=5$
$x=\frac{5}{2}$
c) Subtract 5x from both sides and divide.
$2x=5x+6$
$-3x=6$
$x=-2$
d) Add $4x-11$ to both sides and divide.
$x+11=6-4x$
$5x=-5$
$x=-1$
