I want to know the answer to the problem of 8u=3u+35, can you show me
8u=3u+35----(1)
This is a simple linear equation in the single variable u. Just collect the terms in u on one side and then solve.
(1) implies
8u-3u = 35 (adding -3u to both the sides) (in other words transferring 3u from the right to the left, change side, then change sign is the rule)
5u = 35
u = 35/5 = (7X5)/5 = 7
u=7
Note: The problem is listed under complex_numbers categpry! which is surprising!.There must be some typing mistake in the problem. There is no sign of i the sqroot of (-1) either in the given expression or in the answer. There will be i in the answer after factorising if the given expression is a quadratic one with factors having i terms.
