Question: Solve this expression without using a calculator!?!?!?!?
2x=j but only when j is multiplied by 7 and 6 is added on to it!. If the above statement is true, (which it is) then what is 5x+j=x!?Www@Enter-QA@Com
Answers:
so it's 2x=j and 7j+6=2x,
then 7!.2x+6=2x
14x-2x=-6
12x=-6
x=-2
j=2!.-2=-4
if 5x+j=x,
then 5x-x=-j,
4x=-j,
4!.-2=4,
-8=4
so 5x+j is not equal to xWww@Enter-QA@Com
then 7!.2x+6=2x
14x-2x=-6
12x=-6
x=-2
j=2!.-2=-4
if 5x+j=x,
then 5x-x=-j,
4x=-j,
4!.-2=4,
-8=4
so 5x+j is not equal to xWww@Enter-QA@Com
