what is the answer and the solution in 1/5(4-3x)=1/7(3x-4)

Sagot :

1/5(4-3x) = 1/7(3x-4)
-----------------------------
cross multiply 5 and 7
7(4-3x) = 5(3x-4)
----------------------------
Distribute
28 - 21x = 15x - 20
---------------------------
transpose 15x to the left and 28 to the right
-21x - 15x = -20 - 28
-36x = -48
x = 48/36
x = 4/3
