(a+13)/3 = (a-11)/2
multiply both sides by 6 (which is 3*2)
2(a+13) = 3(a-11) (you call it cross multiplying. I do not like to think that way. I multiply both sides by the least common denominator, 6)
2 a + 26 = 3 a - 33
59 = a
multiply both sides by 6 (which is 3*2)
2(a+13) = 3(a-11) (you call it cross multiplying. I do not like to think that way. I multiply both sides by the least common denominator, 6)
