Hey there!
Simplify both sides of your equation
-9/3 + b = -1
-9/3 = -3
3 + b = -1
Revert: b - 3 = -1
ADD by 3 on your sides
b - 3 + 3 = -1 + 3
Cancel out: -3 + 3 because it gives you 0
Keep: -1 + 3 because it helps us solve for your b
-1 + 3 = b
-1 + 3 = 2
This your answer is: b = 2 ✅
Good luck on your assignment and enjoy your day!
