3x + 5 = -20.
First, subtract 5 from both sides of the equation:
3x + 5 - 5 = -20 - 5; and simplify:
3x = -25. Then divide both sides by 3:
3x / 3 = -25 / 3; and simplify:
x = -8 1/3 (or -8.33)

3x+5 = 2x+13 3x-2x = 13-5 x = 8
if 3x+5=x+19 then x=7
If: 3x+5 = 4x+1 Then: x = 4
3x+5=14 3x=9 x=3
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
