Answer: [tex]b=14[/tex]
Simplify both sides of the equation
[tex](2)(b)+(2)(-4)=20(Distribute)\\2b+-8=20[/tex]
Add 8 to both sides
[tex]2b-8+8=20+8\\2b=28[/tex]
Divide both sides by 2
[tex]2b/2=28/2\\b=14[/tex]
Answer:
[tex]b = 14[/tex]
Step-by-step explanation:
[tex]2(b - 4) = 20 \\ 2b - 8 = 20 \\ 2b = 20 + 8 \\ 2b = 28 \\ \frac{2b}{2} = \frac{28}{2} \\ b = 14[/tex]
