2b/4+b/3=10 solve for b.
If you don't like fractions, then clear them by multiplying each thing by 12. Otherwise, just add fractions with a common denominator like with arithmetic.
what is b
2b/4 + b/3 = 10
you find a common denominator, which is twelve so multiply 2b/4 by 3 and the b/3 by 4, we then get
6b+4b/12 = 10
to get rid of denominator we times both sides by twelve to get
10b = 120
to get rid of b you divide both sides by 10 to get:
b = 12
(don't forget to do opposite operation when moving it to other side) :)
