4b + 5 = 1 + 5b
b=
Answer:
b=4
Step-by-step explanation:
4b + 5 = 1 + 5b
Subtract 4b from each side
4b-4b + 5 = 1 + 5b-4b
5 =1+b
Subtract 1 from each side
5-1 = 1-1+b
4 =b
Steps to solve:
4b + 5 = 1 + 5b
~Subtract 5b to both sides
4b - 5b + 5 = 1 + 5b - 5b
~Simplify
-b + 5 = 1
~Subtract 5 to both sides
-b + 5 - 5 = 1 - 5
~Simplify
-b = -4
~Divide -1 to both sides
-b/-1 = -4/-1
~Simplify
b = 4
Best of Luck!

in the prom?
Answer:
36 girls, 48 boys . Total of 84 in the prom.
Step-by-step explanation:
Let the number of girls be x, then the number of boys is x+12.
So we have the equation:
4/3 = (x + 12) / x
4x = 3x + 36
x = 36.
So there are 36 girls and 48 boys in the prom.
