x + 5y = 15 এবং 5x + 8 = 58 হলে, y এর মান কত?
Solution
Correct Answer: Option B
দেওয়া আছে
5x + 8 = 58
5x = 58 - 8
5x = 50
x = 10
আবার
x + 5y = 15
10 + 5y = 15
5y = 15 - 10
5y = 5
y = 1
y এর মান = 1
5x + 8 = 58
5x = 58 - 8
5x = 50
x = 10
আবার
x + 5y = 15
10 + 5y = 15
5y = 15 - 10
5y = 5
y = 1
y এর মান = 1
