Question

5n-1/4=-1

Answer 1

if you want to solve for a variable
just put in a form

y= whatever variable you have

y = number

Answer 2

1-multiply by 4 to both sides
2-add 1 to both sides
3-divide by 5

Answer 3

EXAMPLE

2X -3 = 4
2X -3 (-3) = 4 +(-3) ADD ADDITIVE INVERSE
1/2 [ 2X = 1 ] MULTIPLY BY RECIPROCAL
X = 1/2 HERE IS YOU ANSWER

CAN YOU NOW TRY THE SAME THING WITH YOU PROBLEM?

Answer 4

But x equals 7/2

Answer 5

is that you answer ?

Answer 6

2x-3=4
2x=4+3
2x=7
X=7/2

Answer 7

@oly.surf

Is this --> 5n-1/4=-1 supposed to be ( 5n - 1 ) / 4 = -1 ?

Answer 8

@oly.surf : right ,X =7/2 Good job :)

Answer 9

you may cancel you fractions

EXAMPLE
multiply by 3

3 4
--- = ---
1 3
it will now be
4

Answer 10

@Eyad I don't know how to do it with my operation, this is what I have so far:
5n-1/4=-1
5n=-1+1/4

Answer 11

you can cancel out the
the fraction if you dont like it

Answer 12

but you just get bigger numbers

Answer 13

@oly.surf : is it like that ?
\[\Huge \frac{(5n-1)}{4}=-1\]

Answer 14

\[5n - \frac{ 1 }{ 4 }=-1\]
it is like this

Answer 15

OH !!
In that case do the following :


1-add 1/4 to both sides ==== > 5n-1/4 +1/4=-1+1/4
it will be ----> 5n=-0.75

2-Divide by 5 ====> 5n/5=-0.75/5
it will be like ---->n=-0.15

Answer 16

got it, it end up being
5n = -3/4
n = -3/4 divided by 5/1
n = -3/4 x 1/5
n = -3/20

Answer 17

@iforgot : why are you confusing him ?
