Question

Please help me
x^2-5x-y-1=2x^2+y-9
find y??

Answer 1

you aim to get y only on one side of the '='
first add y to both sides of the equation
x^2-5x-y-1=2x^2+y-9
+y +y this gives

x^2 - 5x - 1 = 2x^2 +2y - 9

Answer 2

now by subtracting 2x^2 and adding 9 to both sides you'll get 2y on its own on the right hand side

Answer 3

can u do that?

Answer 4

yeah i can

Answer 5

x^2 - 5x - 1 = 2x^2 +2y - 9
- 2x^2 +9 = -2x^2 +9 gives

Answer 6

can you write the next line?

Answer 7

then wats next?

Answer 8

you need to simplify x^2 - 2x^2
and -1 + 9

Answer 9

after you have done the above you divide both sides by 2 ( because you have 2y and you need y)

Answer 10

2y=3x^2-5x+10?

Answer 11

no
2y = -x^2 - 5x + 8
