Solve the equation. Check the solution.

sorry now does it make sense lol
yup ! looks last time u posted a diff q wid these options lol
lol yeah true i copied and pasted it but i forgot to copy the new question lol
\(\huge \frac{-4}{x+1} = \frac{-1}{x+1} \)
wat should be our first step ?
no the bottom on the right is x+5
see that, i have negative both sides. lets cancel them, as i hate negative numbers
was just checking u r alert or not lol ;)
lol yeah im alert trust me good test though
\(\huge \frac{-4}{x+1} = \frac{-1}{x+5} \)
like this right
lets multiply both sides by -1. that gets rid of negatives
okay n yes its right
\(\huge \frac{-4}{x+1} = \frac{-1}{x+5} \) multiply -1 both sides \(\huge \frac{4}{x+1} = \frac{1}{x+5} \)
next, cross multiply u knw how to cross myltiply right ? :)
4x5 and 1x1 right?
who ate x's lol
times lol
\(\huge \frac{-4}{x+1} = \frac{-1}{x+5} \) multiply -1 both sides \(\huge \frac{4}{x+1} = \frac{1}{x+5} \) cross multiply \(\large 4(x+5) = 1(x+1)\)
entire bottom thing (x+5) or (x+1) multiplies wid the cornery tops ok
next, distriibute and simplify a bit
4x+20=1x+2 right
\(1 \times 1 = 1\)
\(1 \times 1 \ne 2\)
yeah ur right sorry 1
ok
im sure u r checking my alerttness nw -.-
\(\huge \frac{-4}{x+1} = \frac{-1}{x+5} \) multiply -1 both sides \(\huge \frac{4}{x+1} = \frac{1}{x+5} \) cross multiply \(\large 4(x+5) = 1(x+1)\) \(\large 4x+20 = x+1\)
next, subtract x both sides
yeah lol how would u do that?
\(\huge \frac{-4}{x+1} = \frac{-1}{x+5} \) multiply -1 both sides \(\huge \frac{4}{x+1} = \frac{1}{x+5} \) cross multiply \(\large 4(x+5) = 1(x+1)\) \(\large 4x+20 = x+1\) subtract x both sides \(\large 4x+20 = x+1\) -x -x \(\large 3x+20 = 1\)
\(\huge \frac{-4}{x+1} = \frac{-1}{x+5} \) multiply -1 both sides \(\huge \frac{4}{x+1} = \frac{1}{x+5} \) cross multiply \(\large 4(x+5) = 1(x+1)\) \(\large 4x+20 = x+1\) subtract x both sides \(\large 3x+20 = 1\) subtract 20 both sides \(\large 3x = -19\) divide 3 both sides \(\large x = -\frac{19}{3}\)
there is the complete solution. Enjoy..
that isnt an option
It's C. Your last choice.
^^ option C :) you sure need to take some rest before moving to next problems... :|
