Question

check my answers please
solve the following equation.
2(h - 8) - h = h - 16 
h = 8
h = -8
infinitely many solutions 
no solution

anonymous · Answer

answer no solution

austinl · Answer

$2(h-8)-h=h-16$

$2h-16-h=h-16$

$h-16=h=16$

$0=0$

Infinitely many solutions!

oh well th would explain why I couldn't figure it out I think I did it wrong but im almost positively positive that 5 + 7x = 11 + 7x has no solutions am I right?

austinl · Answer

$\color{red}{\text{Correction}}$
$h-16=h-16$

austinl · Answer

$5+7x=11+7x$
$5-11=7x-7x$
$-6\ne0$

Correct!

yay

anonymous · Answer

ok which equation ahs no solution? 
8 - (5v + 3) = 5v - 5 has a solution
3m - 6 = 5m + 7 - m has a solution
3w + 4 - w = 5w - 2(w-2) has a solution
7y + 9 = 7y - 6 no solution right

austinl · Answer

Oh dear, that is a bit of work right there.
I would just say solve them all out for the variable. If you have something where "variable"="number" there is a solution.
0=1 no solution
0=0, 1=1, etc. infinitely many solutions.

anonymous · Answer

so am I right like you only have to do the last one and if it has no solution then its most likely right

austinl · Answer

The last one, is indeed no solution.
$0\ne-15$
