Answer:
b = 10
Explanation:
Lets start by combining like terms (b):
3/2b + 1/5b
to combine these fractions you must get them to both have the same denominator:
3/2 · 5/5 = 15/10 multiply top and bottom by other fractions denominator
1/5 · 2/2 = 2/10 multiply top and bottom by other fractions denominator
15/10 + 2/10 = 17/10
17/10b = 17
Now we want to get the b to be by itself, so lets first multiply both sides by 10:
17b = 170
Now lets divide both sides by 17:
b = 10
Hope this helped!
3/2b + 1/5b = 17
Multiply both sides by the LCD. The LCD is 2 * 5 = 10.
10 * 3/2b + 10 * 1/5b = 10 * 17
15b + 2b = 170
17b = 170
b = 10
