Question 93680
Questions:


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/12 = 24/12 }}}



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



Hope you found the explanation useful
