Question

Solve 9x-2y=11 for y

Answer 1

Answer:

y=9/2x-11/2

Step-by-step explanation:

-2y=11-9x

y=11-9x/-2

y=9/2x-11/2

Answer 2

Answer:

y= 9/2x - 11/2

or

y=4.5x -5.5

Step-by-step explanation:

To solve for y, we must get y by itself on one side of the equation.

9x-2y=11

9x is being added to 2y. The inverse of addition is subtraction. Subtract 9x from  both sides.

9x-9x -2y= 11-9x

-2y= 11-9x

y is being multiplied by -2. The inverse of multiplication is division. Divide both sides by -2.

-2y-/2= 11-9x/-2

y= 11/-2 - 9x/-2

y=- 11/2 +9/2 x

or

y= -5.5 +4.5 x

Reorder the terms.

y= 9/2x - 11/2

or

y=4.5x -5.5
