Question

G= 1+2a/a , solve for a

Answer 1

G=3
Explanation: G=1+2a/a
1+2a/a=G
Simplify
1+2a(1/a)=G
cancel out the common factor of a
1+2/1*1/1=G
1+2=G
G=3

Answer 2

Answer: a = 1/(g-2)

Explanation: We must solve the equation

g =  1 + 2a/a

if the equation is as written, then a/a cancels itself, because a/a = 1, and in that case we can not solve the equation for a:

g = 1 + 2a/a = 1 + 2 = 3

if the equation is, instead:

g = (1 + 2a)/a = 1/a + 2

we can solve it for a, wich means isolating a in one side of the equation, i will do it step by step.:

g = 1/a + 2

g - 2 = 1/a

a(g - 2) = 1

a = 1/(g-2)
