Question

X^2+4x-9=x+1 i have no idea what the answer would be

Answer 1

x = 2

Explanation:

Simplify both sides of the equation.

`x(2)+4x-9=x+1\\2x+4x+-9=x+1\\(2x+4x)+(-9)=x+1` (combine like terms)

`6x+-9=x+1\\6x-9=x+1\\`

subtract x from both sides.

`6x-9-x=x+1-x\\5x-9=1`

add 9 to both sides.

`5x-9+9=1+9\\5x=10`

divide both sides by 5

`(5x)/(5) =(10)/(5) \\x=2`
