Question

v-e+f=2

Answer 1

plz assist in solving

Answer 2

what variable are you solving for?

Answer 3

solving for V E and F v-e+f=2

Answer 4

well lets solve fot v first

v-e+f=2

add e to both sides and take f from both sides

Answer 5

plz show answer step by step, many thanks

Answer 6

v-e+f+e-f = 2+e-f
... = ....

Answer 7

if we substitute 1/2 (half) - so we get 2 on both sides of equation, is that also correct, plz advise

Answer 8

there will be no substitution in this question

Answer 9

after you have got
v-e+f+e-f = 2+e-f

you just need to simplify the lefthandside

Answer 10

ok, simplify left hand side for me plz, and i can see final answer
thank you, appreciate it

Answer 11

you can do it

Answer 12

im clueless, i just wanted to see the answer step by step

Answer 13

v-e+f+e-f

if you rearrange this

you can get

v+(f-f) +(e-e)

Answer 14

ok thank you appreciate it

Answer 15

v-e+f+e-f = 2+e-f
v+(f-f) +(e-e) = 2+e-f

is this the final answer

Answer 16

tell me what those terms in the brackets simplify to --

Answer 17

im clueless, i have no idea, thats why i need help in this

Answer 18

ok we will look at one set of brackets at a time
can you simplify
f-f

Answer 19

(imagine that f is some number)

Answer 20

f-f to me means nothing or zero

Answer 21

right f-f=0

Answer 22

and (e-e) = ?

Answer 23

e-e is also 0 to my knowledge - zero

Answer 24

that is right

Answer 25

so what is v+(f-f) +(e-e)

Answer 26

V+0 + 0 = V

Answer 27

correct

Answer 28

the reason that we added e to both sides and took f from both sides was to get the left hand side to cancel to just leave us with v=

Answer 29

v-e+f+e-f = 2+e-f
v+(f-f) +(e-e) = 2+e-f

is this the final answer
so V=2

Answer 30

hmm not quite

Answer 31

so 2=2

Answer 32

Let's start again,

v-e+f = 2

what do you get when to add e to both sides of the equation
and takeaway f from both side of the the equation

Answer 33

we left with a V

Answer 34

yes, the lefthand side of the equation is simply v, but what is the right hand side of the equation?

Answer 35

2+e-f

Answer 36

so you have shown \[v=2+e-f\large\color{red}\checkmark\]

Answer 37

oh ok, that is the final answer, thanks so much, now i understand, thanks you

Answer 38

now lets solve for e

Answer 39

i know the answers thanks

Answer 40

e=2-f-v

Answer 41

not quite

Answer 42

f=2+e-v

Answer 43

you have got f right

Answer 44

e=2+f-v

Answer 45

If we start from the original equation

v-e+f=2

add e to both sides and take away 2 from both sides

Answer 46

v+f-2=0+e

Answer 47

right , now just simplify the right hand side
