Question

(5x - 1)/2 + (-3x - 1)/4 = 9/2

Answer 1

lets clear the fractions... multiply the whole equation by 4...
\[\large \frac{5x-1}{2}+\frac{-3x-1}{4}=\frac{9}{2} \]
\[\large 4\times(\frac{5x-1}{2}+\frac{-3x-1}{4}=\frac{9}{2}) \]
\[\large 2(5x-1)+(-3x-1)=2*9 \]

can you take it from here?

Answer 2

im lost.. :/

Answer 3

use this property\[\LARGE{\color{red}{2(a+b)=2a+2b.}}\]
This is what that @dpaInc has done:)

Answer 4

10x - 1 + -6x-2 = 18 ? idk im confused

Answer 5

It means distributive law of property.
Only difference is that @dpaInc has use 4 instead of 2

Answer 6

k! \[\color{green}{4x-3=18\implies x=\frac{21}{4}.}\]

Answer 7

this is the further solution:)

Answer 8

so thats my answer? im so lost! haha i hate math

Answer 9

ya its ur answer :-)

Answer 10

sorry wait a minute u have multiplied the equation wrong :/

Answer 11

10x - 1 + -6x-2 = 18 is wrong.
The right is 10x-2-3x-1=18.
now do it.

Answer 12

how would i solve that? :/

Answer 13

7x-1= 18?

Answer 14

just as i did before for wrong eq.

Answer 15

no it is nt this
try again

Answer 16

idk how to do it then :/

Answer 17

-1-2=-3
so ur eq. will become
7x-3=18.
x=21/7.
& for ur information it is ur answer:-)
