Answer:
Answer is 24
Explanation:
Multiply by the l.c.m which is 4.
-20+3b = 52
3b = 52+20
3b = 72
b = 24
Answer: b = 24
-5 + 3/4b = 13
Add 5 to each side
3/4b = 18
Now, we know that 3/4 = 0.75, so divide each side by 0.75
We can also plug this into the equation to check it.
-5 + 3/4(24) = 13
3/4(24) = 18
-5 + 18 = 13
13 = 13
