Answer:
[tex]b=3[/tex]
Step-by-step explanation:
Given equation:
[tex]1+2b-13=12-4b-2b[/tex]
Solving for [tex]b[/tex]
Combining like terms on both sides.
[tex]2b+1−13=12-4b-2b[/tex]
[tex]2b-12=12-6b[/tex]
Adding [tex]6b[/tex] both sides to get [tex]b[/tex] terms on one side.
[tex]2b-12+6b=12-6b+6b[/tex]
[tex]8b-12=12[/tex]
Adding 12 both sides to isolate [tex]b[/tex] on one side.
[tex]8b-12+12=12+12[/tex]
[tex]8b=24[/tex]
Dividing both sides by 8.
[tex]\frac{8b}{8}=\frac{24}{8}[/tex]
∴ [tex]b=3[/tex] (Answer)
