To solve this, first add -9b on both sides of the equation to get the variable on only one side of the equation.
2b+4=-18-9b
2b+9b+4=-18-9b+9b
11b+4=-18
Then subtract 4 from both sides of the equation.
11b+4=-18
11b+4-4=-18-4
11b=-22
Divide 11 on both sides of the equation to find the values of b.
[tex]\frac{11b}{11}[/tex]=[tex]\frac{-22}{11}[/tex]
b=-2
