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. $x+11=6-4x$ $5x=-5$ $x=-1$
