5(x-4)-1=-7x+3

Answer:

5(x-4)-1=-7x+3
First remove the parenthesis..

5*x - 5 * 4 - 1 = -7x + 3

==> 5x - 20 - 1 = -7x + 3

==> 5x - 21 = -7x + 3


Add 7x on both sides....

==> 5x - 21 + 7x = -7x + 3 + 7x

==> 12x - 21 = 3


Add 21 on both sides...



==> 12x - 21 + 21 = 3 + 21


==> 12x = 24


Divide both sides by 12.

==> +12x%2F12+=+24%2F12+


==> x = 2, which is the required solution.


Hope you found the explanation useful
