-14 + 6b + 7 - 2b= 1 + 5b
combine like terms
-7 +4b = 1 + 5b
subtract 4b from each side
-7 + 4b -4b = 1 + 5b -4b
-7 = 1 + b
subtract 1 from each side
-7 -1 = 1-1 + b
-8 = b
Are these 2 different questions
Answer:
Total number of notes is 11.
Step-by-step explanation:
Value is 100 rupees…
5x + 20y = 100 and x + y = 11 are the two equations.
We can simplify…
5x + 20 y - 5x - 5y = 100 - 55 = 45
15y = 45 so y = 3
x = 11 - y = 8
So, we have 8 notes of 5 rupees denomination and 3 notes of 20 rupees denomination.
I hope it helps you.
