Equation: [tex]7b-3=-2b+24[/tex]

When solving these type of equations, you have to get the variable on one side by "itself".

To start off, add 2b to both sides

[tex]7b+2b-3=-2b+2b+24[/tex]

Now add 3 to both sides

[tex]9b-3+3=24+3[/tex]

It is now [tex]9b=27[/tex]

Now divide 27 by 9 (don't worry about the variable because you're dividing to FIND the variable value)

[tex]27[/tex] ÷ [tex]9=3[/tex]

Answer: [tex]b=3[/tex]
