Question

PLEASE HELP! 7v-1/2=6/5v-3/5

Answer 1

5(7v-1/2) = 5(6/5v-3/5)
35v-5/2=6v-3
29v= 3+5/2
v= 11/2/29
v=11/58

Answer 2

that is incorrect :/

Answer 3

I like to get rid of fractions so multiply both sides by 10
so we have
70v-5=12v-6
70v-12v=-6+5
58v=-1
v=-1/58

Answer 4

Yep, it should be -1/58

Answer 5

ok what about 1/5w+4/3=7/3w-4 ??

Answer 6

like i said i like to get rid of the fractions multiply both sides by 15
3w+20=35w-60
3w-35w=-60-20
-32w=-80
w=80/32=5/2

Answer 7

what do u mean by both sides?

Answer 8

what do u multiply by 15?

Answer 9

By both sides myininaya probably means to multiply the terms on the right and left of the = sign by that amount.

Answer 10

i'm confused :/

Answer 11

can you show me with this example?
5/4*u+3/4=1/3*u+7

Answer 12

you don't have to get rid of the fractions
you could just work with them
w/5-7w/3=-4-4/3
(3w-35w)/15=(-12-4)/3
-32w/15=-16/3
w=(-16/3)(15/-32)=5/2

Answer 13

see like this one....u multiply every single fraction by 15 to get rid of the fractions?

Answer 14
