Question

Make x the subject
y = (2x-1)/(x+3)

Answer 1

\[y=\frac{ 2x-1 }{x+3 }\]

Answer 2

X= -10,-4,-2,4
Y=3,9,-5,1

Answer 3

as a first step, multiply both sides by (x+3) like this:
\[ y\cdot (x+3)=\frac{ 2x-1 }{x+3 } \cdot (x+3) \]

Answer 4

Yes I've done that but I don't know to how continue ...

Answer 5

what do you get after simplifying the right side ?

Answer 6

I solved for x and y, they have more than one solution.

Answer 7

y(x+3)=2x-1

Answer 8

make xs in one side and ys the otherside

Answer 9

We're making x the subject not solving...

Answer 10

now distribute the y : multiply each term in the parens by y

Answer 11

yx + 3y = 2x-1

Answer 12

I would add -yx to both sides
and add +1 to both sides

Answer 13

3y+1=2x-yx?

Answer 14

almost done... factor out the x from each term on the right side

Answer 15

factoring x out is the opposite of "distributing"

Answer 16

3y+1=x(2-y)
x=(3y+1)/(2-y)

Answer 17

yes

Answer 18

Thank you for your help!
