Solve the literal equation for a
y=x(ab/ab)

Hi Helen, this is easy!
Solving the literal equation for 'a' means expressing the equation in terms of a.
Let us see the solutions step by step:
a) Multiplying the denominator ab with y gives : y(ab) = xab
b)Expanding the parentheses y(ab) gives yayb = xab
c)Since ya and xab have 'a', the equation is now rearranged as:
yaxab = yb
d)Taking out the 'a' from yaxab
yaxab = a(yxb)
e) a(yxb) = yb
a = yb/(yxb)> final answer
