Answer: b = -4/7
Step-by-step explanation: To solve for b, we must isolate the variable. This can be done in small steps:
First, we rewrite the problem:
[tex]7b \ - \ 4 \ = \ -8[/tex]
Next, we add 4 to both sides:
[tex]7b \ - \ 4 \ + \ 4 \ = -8 \ + \ 4 \ or \ 7b \ = \ -4[/tex]
Finally, we divide by the coefficient (7):
[tex]b \ = \frac{-4}{7}[/tex]
Therefore, b = -4/7.
1. Add 4 to both sides of the equation to isolate the 7b term:
7b - 4 + 4 = -8 + 4
Simplify to get 7b = -4 .
2. Divide both sides by 7 to solve for b:
7b/7 = -4/7
Simplify to find b = -4/7
1. Add 4 to both sides of the equation to isolate the 7b term:
