Question

(2x+1).(4y+1)

Answer 1

8xy+2x+4y+1.. what do you need to do with this?

Answer 2

Can you help me

Answer 3

you have to tell me what you need first xD

Answer 4

Search y and x

Answer 5

but that needs to be equal to something...

Answer 6

()()=...

Answer 7

=4

Answer 8

8xy+2x+4y+1=4
2x+8xy+4y=3
2(x+4xy+2y)=3
are you sure this is all you have?

Answer 9

Ýe

Answer 10

Yes

Answer 11

Huhuhuhu

Answer 12

And it in Z

Answer 13

2x+8xy+4y +1-1=4-1
0+2x+8xy+4y=3
2x+8xy+4y-3=3+ (-3)
2x+8xy+4y-3=0
x(2+8y)+4y-3=0
x(2+8y)=3-4y
x=3-4y/2+8y

Answer 14

X=? Y=?

Answer 15

put x in this equation 2x+8xy+4y-3=0 and solve it

Answer 16

x=3/2 and y=0

Answer 17

Can you help me more

Answer 18

X(y+2)+y=1

Answer 19
