Solve (find the value for the given variable) Show all work and check answers.
a+1/6 = 2/a
5/3x+1 = 3/3x-1 This question is from textbook

Solve (find the value for the given variable) Show all work and check answers.
Assume it's (brackets would help alot)
=
Cross multiply
a(a+1) = 2*6
a^2 + a = 12
a^2 + a - 12 = 0
Factor
(a-3)(a+4) = 0
a=-4
a=+3
I'll let you check both solutions in the original equation
:
=
cross multiply
5(3x-1) = 3(3x+1)
15x - 5 = 9x + 3
15x - 9x = 3 + 5
6x = 8
x =
x = 1
:
Check solution by substituting 8/6 in original equation
