If x[-3{-6(-a)}]+6[-3{-3(-a)}]=6a, then find x.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e.  −103- {{10} \over 3}

Given that

If x[ -3 { -6 (-a )}] + 6[ -3{ -3( -a )}] = 6a

x[ -3 {6a }]+ 6[-3{3a}] = 6a

x[ -18a ]+ 6[ -9a ] = 6a

-18ax - 54a = 6a

18ax = - 60 a

x = -10/3
