8 - 5b = -7 ?? whats the b

Sagot :

Answer:

b=3

Step-by-step explanation:

Isolate the b:

  • 8-5b=-7
  • Subtract 8, -5b=-15
  • Divide by -5, b=3

Check your answer:

  • 8-5(3)=-7
  • 8-15=-7
  • -7=-7
b=3
you subtract the 8 from the left then subtract it from the right giving you -5b=-15 then divide the -5 by both sides
