Question

Help me now! PLEASE
Solve the following simultaneous equation using the substitution method:
y+1=2x
y=x+2
ASAP please!

Answer 1

y+1=2x
replace y with x+2:
x+2 + 1 = 2x
x=3
y=2x-1
y=5

Answer 2

well that the answer :) good luck

Answer 3

Help me with this one as well!
3x+8y=24
x+y=3
pleaseeeeeeeeeeeeeeeeee

Answer 4

ANyone?

Answer 5

i only know that one by elimination sorry

Answer 6

oh sorry i thought that it was a plus sign now thats possible

Answer 7

Help me? please? and quick?:S

Answer 8

take the second equation an make x the subject of the formula x=3/y
Afterwards replace the x value with 3/y to find y.
After finding y raka u then substitute y value on the secon equation to find x simple:)

Answer 9

Can you just do the whole just like Abermejo did on top? :S please?

Answer 10

x+y=3 tomake x the subject we have x=3-y
Now since 3x/8y=24
=3(3/y/8y)=24
=9/y/8y=24
simplying this further we get
9/y*8y=24
=8y^2/9=24
and then multiply by 9 both sides tog
8y^2=216
the divide by 8 both sides
to get y^2=27
then take the sqrt both sides
to get your y as=5.196
=5.2
Afterward u take this y value put it in the second equation to find ur x value x+y=3
x+5.2=3
x=-2.2

Answer 11

please copy this down in ur paper for u to understand properly

Answer 12

feel free to ask any unclear thing

Answer 13

rika a u still there.sry I made a huge blander i thought that it was + was division sign again. y=3-x from second equation now take that y and replace it with the y on the first equation =3x+3-x=24
=2x=21
x=21/2
x=10.5

for your y
x+y=3
10.5+y=3
y=7.5

Answer 14

y=-7.5 sry

Answer 15

answer is apparently wrong :\
y is 3 and x is 0

Answer 16

there are many ways of killing a cat substitute my x and y valu on the second equation u`ll still get 3 10+(-7.5)=3

Answer 17

Alright thanks pal

Answer 18

Gud luck :)
