Answer:
b = 8
Step-by-step explanation:
1.3b + 2 = 12.4
- Subtract 2 from both sides
1.3b = 12.4 - 2
- Subtract 2 from 12.4 to get 10.4.
1.3b = 10.4
- Divide both sides by 1.3.
b = [tex]\frac{10.4}{13}[/tex]
- Expand [tex]\frac{10.4}{13}[/tex] by multiplying both numerator and the denominator by 10.
[tex]b = \frac{104}{13}[/tex]
- Divide 104 by 13 to get 8.
