Help please, Algebra 1- Solving Rational Expressions



2c 4
--- - 2 = -----
c-4 c + 5

Answer 1

you have to put everything with the same denominator first.
Then i'll help you with the remaining equation

Answer 2

Try multiplying both sides by \((c-4)(c+5)\) and simplify a bit.

Answer 3

\[\frac{ 2c }{ c-4 }-2=\frac{ 4 }{c+5 }\]
\[\frac{ 2c-2\left( c-4 \right) }{c-4 }=\frac{ 4 }{ c+5 }\]
\[\frac{ 2c-2c+8 }{ c-4 }=\frac{ 4 }{ c+5 }\]
\[or \frac{ 8 }{ c-4 }=\frac{ 4 }{ c+5 }\]
\[8\left( c+5 \right)=4\left( c-4 \right)\]
or 8c+40=4c-16
or 8c-4c=-16-40
or 4c=-56
or c=-56/4=-14
