Question

6y-5=-3(2y+1)

Answer 1

surrely by now u have realised how to solve these question?

Answer 2

nope. alegbra loses me as soon as i open the book

Answer 3

the reason i have been supplying working out in my responses ... is so u can try a different question whilst following the steps taken to solve it

Answer 4

6y-5=-6y-3
12y=2
y=1/6

Answer 5

see how jhonyy has expanded the brckets first ... this is always the first step.

Answer 6

6y-5= -6y - 3, 12y = 2, y = 1/6

Answer 7

yes i get that and thank you for trying but i really dont understand math whats so ever

Answer 8

after this u need to subtract/add different things to both sides

Answer 9

angea .. tell me how would u solve this for x...
2x = 6

Answer 10

divide 2 by both sides?

Answer 11

correct ... it becomes
2x/2 = 6/2 now on the left side the twos cancel on the fractionto 1 and 6/2 to 3
giving
x=3

Answer 12

but if i had 2x -4 = 6 then we would first have to ADD 4 to both sides, (adding so we can get rid of the negative term - because we cannot add a number and x together)

Answer 13

yes, thats simple. but equations like the one stated above loses me

Answer 14

when u understand it it becomes all manipulation

Answer 15

2x +2=x here we have an x on both sides ... so we need to subtract an x
ill write out exactly what im going to do
2x-x+2 = x-x (this is still equal because we did it to both sides)
becoming
x+2=0
now sunbtract 2 from both sides similar to before to get:
x=-2

Answer 16

still simple enough that i get it. lol

Answer 17

well this is only one step shigh of what your questions are asking ... the only thing different is that your Q's have brackets in them, can you expand brackets?

Answer 18

2(x+3)=x

Answer 19

u need to multiply everything within the brackets by 2 giving:
2x +6 = x this is now the same as before ...
the key with algebra is to understand that what u are doing with big equations is just using a lot of small manipulations to get a result

Answer 20

no sir lol

Answer 21

ahh so its expanding brackets that u need (lol and sir? im only 19)

Answer 22

well brackets are expanded by multiply everything within the brackets by whatever number is out the front
ie: 2(x+1)
now this is the same as
2(x) +2(1)
giving
2x + 2

Answer 23

sorry ive got to go ... if u still have a question ill b bak in about 2 hrs so just leave it on this thread
